Antihyperglycemic activities of cryptolepine analogues: An ethnobotanical lead structure isolated from Cryptolepis sanguinolenta

Cryptolepine (1) is a rare example of a natural product whose synthesis was reported prior to its isolation from nature. In the previous paper we reported the discovery of cryptolepine’s antihyperglycemic properties. As part of a medicinal chemistry program designed to optimize natural product lead structures originating from our ethnobotanical and ethnomedical field research, a series of substituted and heterosubstituted cryptolepine analogues was synthesized. Antihyperglycemic activity was measured in vitro and in an NIDDM mouse model to generate the first structure-bioactivity study about the cryptolepine nucleus.

Schmidt reaction in ionic liquids: Highly efficient and selective conversion of aromatic and heteroaromatic aldehydes to nitriles with [BMIM(SO3H)][OTf] as catalyst and [BMIM][PF6] as solvent

A mild and selective method is presented for the conversion of aromatic and heteroaromatic aldehydes to nitriles via the Schmidt reaction with TMSN 3 by using [BMIM(SO3H)][OTf] as catalyst and [BMIM][PF6] as solvent. The method offers high yields and simple product isolation, and avoids the use of liquid superacids or corrosive Lewis acids commonly employed for this transformation. It also offers some potential for recycling/reuse of the IL solvent.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application of 19012-03-4, you can also check out more blogs about19012-03-4

Enantioselective organo-SOMO cascade cycloadditions: A rapid approach to molecular complexity from simple aldehydes and olefins

A highly selective, radical-mediated (4 + 2) coupling reaction of aldehydes and conjugated olefins has been achieved through asymmetric SOMO-catalysis. A radical-polar crossover mechanism is proposed wherein olefin addition to a transient enamine radical cation and oxidation of the resulting radical furnishes a cation which is vulnerable to nucleophilic addition. A range of aromatic aldehydes are shown to couple with styrenes and dienes to provide cyclic products with high chemical efficiency, regioselectivity, and stereoselectivity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Direct and highly enantioselective iso-Pictet-Spengler reactions with alpha-ketoamides: Access to underexplored indole core structures

Direct, one-pot, operationally simple, and highly enantioselective iso-Pictet-Spengler reactions are reported. The reactions involve the condensation of either (1H-indol-4-yl)methanamine or 2-(1H-Indol-1-yl)ethanamine with a variety of alpha-ketoamides, followed by the addition of a simple and commercially available chiral silicon Lewis acid. These reactions are the first asymmetric examples of these cyclization modes and provide access to 3,3-disubstituted-1,3,4,5-tetrahydropyrrolo[4,3,2-de]isoquinolines and 1,1-disubstituted-1,2,3,4-tetrahydropyrazino[1,2-a]indoles, respectively, two relatively underexplored indole-based core structure motifs in medicinal chemistry.

Chirality in the absence of rigid stereogenic elements: The design of configurationally stable C3-symmetric propellers

Residual stereoisomerism is a form of stereoisomerism scarcely considered so far for applicative purposes, though extremely interesting, since the production of stereoisomers does not involve classical rigid stereogenie elements. In three-bladed propeller-shaped molecules, a preferred stereomerization mechanism, related to the correlated rotation of the rings, allows the free interconversion of stereoisomers inside separated sets (the residual stereoisomers) that can interconvert through higher energy pathways. In light of possible future applications as chiral ligands for transition metals in stereoselective processes, some C3-symmetric phosphorus-centered propellers, which could exist as residual enantiomers, are synthesized and the possibility of resolving their racemates into residual antipodes is explored. While the tris(aryl)methanes are configurationally stable at room temperature, only selected tris(aryl)phosphane oxides display a configurational stability high enough to allow resolution by HPLC on a chiral stationary phase (CSP HPLC) at a semipreparative level at room temperature. Stability was evaluated through different techniques (circular dichroism (CD) signal decay, dynamic CSP HPLC (CSP DHPLC), dynamic NMR analysis (DNMR)) and the results compared and discussed. Phosphanes were found much less stable than the corresponding phosphane oxides, for which preliminary calculations suggest that the three-ring-flip enantiomerization mechanism (M0) would be easier than phosphorus pyramidal inversion. The parameters affecting the configurational stability of the residual enantiomers of C3-symmetric propellers are discussed.

Palladium-catalyzed c(sp2)-n bond cross-coupling with triaryl phosphates

The first general palladium-catalyzed amination of aryl phosphates is described. The combination of MorDalPhos with [Pd(-cinnamyl)Cl]2 enables the amination of electron-rich, electron-neutral, and electron-poor aryl phosphates with a board range of aromatic, aliphatic, and heterocyclic amines. Common functional groups such as ether, keto, ester, and nitrile show an excellent compatibility in this reaction condition. The solvent-free amination reactions are also successful in both solid coupling partners. The gram-scale cross-coupling is achieved by this catalytic system.

Molecular recognition in the P2Y14 receptor: Probing the structurally permissive terminal sugar moiety of uridine-5?-diphosphoglucose

The P2Y14 receptor, a nucleotide signaling protein, is activated by uridine-5?-diphosphoglucose 1 and other uracil nucleotides. We have determined that the glucose moiety of 1 is the most structurally permissive region for designing analogues of this P2Y14 agonist. For example, the carboxylate group of uridine-5?-diphosphoglucuronic acid proved to be suitable for flexible substitution by chain extension through an amide linkage. Functionalized congeners containing terminal 2-acylaminoethylamides prepared by this strategy retained P2Y14 activity, and molecular modeling predicted close proximity of this chain to the second extracellular loop of the receptor. In addition, replacement of glucose with other sugars did not diminish P2Y14 potency. For example, the [5??]ribose derivative had an EC50 of 0.24 muM. Selective monofluorination of the glucose moiety indicated a role for the 2??- and 6??-hydroxyl groups of 1 in receptor recognition. The beta-glucoside was twofold less potent than the native alpha-isomer, but methylene replacement of the 1??-oxygen abolished activity. Replacement of the ribose ring system with cyclopentyl or rigid bicyclo[3.1.0]hexane groups abolished activity. Uridine-5?-diphosphoglucose also activates the P2Y2 receptor, but the 2-thio analogue and several of the potent modified-glucose analogues were P2Y14-selective.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 473257-60-2, and how the biochemistry of the body works.Synthetic Route of 473257-60-2
