The first enantioselective total synthesis of (-)-petromindole, an architecturally distinct congener of indole diterpene family, has been achieved. Key features of this synthetic route include the scalable and concise synthesis of tricyclic allylic alcohol from enantiopure Wieland-Mischer ketone derivative, and TMSOTf-mediated, highly efficient biomimetic C-4 cyclization of indole derivative for the rapid Construction of a hexacyclic skeleton of petromindole.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 21799-87-1 help many people in the next few years. SDS of cas: 21799-87-1.

Dietary fibre intake is low in paediatric chronic kidney disease patients but its impact on levels of gut-derived uraemic toxins remains uncertain

Background Chronic kidney disease (CKD) in children is a pro-inflammatory condition leading to a high morbidity and mortality. Accumulation of organic metabolic waste products, coined as uraemic toxins, parallels kidney function decline. Several of these uraemic toxins are protein-bound (PBUT) and gut-derived. Gut dysbiosis is a hallmark of CKD, resulting in a state of increased proteolytic fermentation that might be counteracted by dietary fibre. Data on fibre intake in children with CKD are lacking. We aimed to assess dietary fibre intake in a paediatric CKD cohort and define its relationship with PBUT concentrations. Methods In this multi-centre, cross-sectional observational study, 61 non-dialysis CKD patients (9 +/- 5 years) were included. Dietary fibre intake was assessed through the use of 24-h recalls or 3-day food records and coupled to total and free levels of 4 PBUTs (indoxyl sulfate (IxS), p-cresyl sulfate (pCS), p-cresyl glucuronide (pCG) and indole acetic acid (IAA). Results In general, fibre intake was low, especially in advanced CKD: 10 +/- 6 g/day/BSA in CKD 4-5 versus 14 +/- 7 in CKD 1-3 (p = 0.017). Lower concentrations of both total (p = 0.036) and free (p = 0.036) pCG were observed in the group with highest fibre intake, independent of kidney function. Conclusions Fibre intake in paediatric CKD is low and is even worse in advanced CKD stages. Current dietary fibre recommendations for healthy children are not being achieved. Dietary management of CKD is complex in which too restrictive diets carry the risk of nutritional deficiencies. The relation of fibre intake with PBUTs remains unclear and needs further investigation.

Metal-Free Multicomponent Construction of Tetrahydroisoquinoline-Indole Derivatives via In Situ Generated ortho-Quinonoid Intermediate

A metal- and ligand-free multicomponent coupling of tetrahydroisoquinoline (THIQ), ortho-hydroxybenzaldehydes and indoles under solvent-free conditions is described. The developed protocol provided a waste-free and concise access to C(1)-functionalized THIQ-indole derivatives under green conditions. The reactant molar ratio and neutral conditions were found crucial for controlling the selectivity of desired THIQ-indole product over competitive by-products i. e. oxazine and bis(indolyl)methane. The experimental and DFT study revealed the involvement of ortho-quinonoid species which reacts with indoles in situ to form THIQ-indole derivatives.

Iridium-Catalyzed Direct C4-and C7-Selective Alkynylation of Indoles Using Sulfur-Directing Groups

Indoles and their analogues have been one of the most ubiquitous heterocycles during the past century, and extensive studies have been conducted to establish practical synthetic methods for their derivatives. In particular, selective functionalization of the poorly reactive benzenoid core over the pyrrole ring has been a great challenge. Reported herein is an iridium-catalyzed direct alkynylation of the indole C4- and C7-positions with the assistance of sulfur directing groups. This transformation shows a wide range of functional-group tolerance with exceptional site selectivity. The directing group can be either easily removed or transformed after catalysis. The synthetic utility of the alkyne fragment is demonstrated by the derivatization into the core structure of natural indole alkaloids.
