An atom economic direct synthesis of carbazoles having aryl and keto-aryl groups has been achieved through Pd(II)-catalyzed cascade reactions between 1-(indol-2-yl)-3-butyn-1-ols and aldehydes. The reaction proceeds through alkyne-carbonyl metathesis, an uncommon pathway using palladium catalyst, and constitutes a fast intermol. assembly through four carbon-carbon bond formations in one-pot. Absence of the aldehyde substrate resulted in the formation of C1-aryl substituted carbazoles. The reaction is amenable to the synthesis of bis-carbazole derivatives

Indole and indoline rings are important pharmacophoric scaffolds found in marketed drugs, agrochems., and biol. active mols. The [2 + 2] cycloaddition reaction is a versatile strategy for constructing architecturally interesting, sp³-rich cyclobutane-fused scaffolds with potential applications in drug discovery programs. A general platform for visible-light mediated intermol. [2 + 2] cycloaddition of indoles with alkenes has been realized. A substrate-based screening approach led to the discovery of tert-butyloxycarbonyl (Boc)-protected indole-2-carboxyesters as suitable motifs for the intermol. [2 + 2] cycloaddition reaction. Significantly, the reaction proceeds in good yield with a wide variety of both activated and unactivated alkenes, including those containing free amines and alcs., and the transformation exhibits excellent regio- and diastereoselectivity. Moreover, the scope of the indole substrate is very broad, extending to previously unexplored azaindole heterocycles that collectively afford fused cyclobutane containing scaffolds that offer unique properties with functional handles and vectors suitable for further derivatization. DFT computational studies provide insights into the mechanism of this [2 + 2] cycloaddition, which is initiated by a triplet-triplet energy transfer process. The photocatalytic reaction was successfully performed on a 100 g scale to provide the dihydroindole analog.

The solid state and fluxional behaviors in solution of complexes L²AlOBn and L⁷AlOBn (Bn = benzyl) supported by an analog of salen incorporating indolide arms connected via their 2- and 7-positions were defined by experiment and theory. The complexes catalyze the stereoselective conversion of rac-lactide (rac-LA) to isotactically enriched polylactide. A key aspect of the stereocontrol was examined through study of the initiation reactions via NMR spectroscopy, X-ray crystal structures of the ring-opened products, and theory. The results include the first unambiguous structural definition of stereocontrol in ring-opening of LA by a metal-alkoxide complex and the finding that definition of the stereochem. of initiation by the studied system is governed thermodynamically rather than kinetically.

ST4 produces variety of active compounds to interfere fungal sexual mating and hyphal growth》, the research content is summarized as follows. Sexual mating of compatible sporida is essential for Sporisorium scitamineum to form dikaryotic mycelia and then cause infection on sugarcane. Our previous work identified a Pseudomonas sp. ST4 from a soil sample, which showed a promising biocontrol potential by inhibiting the mating of S. scitamineum sporida and hyphal growth. In this study, we set to isolate the active compounds from Pseudomonas sp. ST4 through solid fermentation High-performance liquid chromatog. (HPLC) separation coupling with bioassay showed that Pseudomonas sp. ST4 produced a range of antimicrobial compounds Two of the major components were purified following acetate extraction, silica gel and HPLC separation NMR (NMR) and liquid chromatog.-mass spectrometry (LC-MS) anal. identified these active compounds are 4-hydroxybenzaldehyde and indole-3-carbaldehyde resp. Further anal. showed that the former compound only inhibited the hyphal growth of the fungus at a concentration of 3 mM, while the latter interfered the fungal sexual mating at a concentration of 0.6 mM and affected hyphal growth at a concentration of 2 mM. Treatment of corn plants with 3 mM indole-3-carbaldehyde significantly inhibited corn smut infection, with a control rate up to 94%. Further anal. of the structure and activity relationship revealed that indole has a much stronger inhibitory activity against the fungal sexual mating than indole-3-carbaldehyde. The results from this study provide new agents for control and prevention of the sugarcane smut disease, and the active compounds could also be used to probe the mol. mechanisms of fungal sexual mating.
