Article Abstract
Halosulfonylation of terminal alkynes was achieved with sulfonylhydrazides as the sulfonyl precursor and inexpensive iron halide as halide source in the presence of TBHP, allowing the regio- and stereoselective generation of (E)-β-chloro and bromo vinylsulfones.

Exploring extreme environments in Türkiye for novel P450s through metagenomic analysis.

Cytochrome P450 enzymes (P450s), particularly those of microbial origin, are highly versatile biocatalysts capable of catalyzing a broad range of regio- and stere-oselective reactions. P450s derived from extremophiles are of particular interest due to their potential tolerance to high temperature, salinity, and acidity. This study aimed to identify and classify novel microbial P450 enzymes from extreme environments across Türkiye, including hydrothermal springs, hypersaline lakes, and an acid-mine drainage site.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are antidiabetic drugs developed using phlorizin, a natural glucoside, as the lead compound. Chemical glycosylation requires multi-step reactions involving protection and deprotection steps, posing challenges in terms of regioselectivity and environmental burden due to the use of hazardous reagents and harsh conditions. In contrast, enzymatic glycosylation using UDP-glucosyltransferases (UGTs) enables regio- and stereoselective glycosylation under mild conditions without protection and deprotection steps.

A regio-, diastereo-, and enantioselective cobalt-catalyzed C-H activation/annulation of aromatic and alkenyl amides has been developed to access heterocycles featuring vicinal C-C and C-N diaxes. This strategy uniquely harnesses previously unexplored electronically unbiased internal alkynes and proceeds under mild conditions to deliver products in high yields with excellent regio- and stereocontrol.

Herein, we report an optimized Pd/Cu bimetallic catalyst that facilitates the stereoselective allylic alkylation of secondary and tertiary nitriles under mild conditions. This method affords homoallylic nitriles with adjacent tri- and tetrasubstituted stereocenters. Using both racemic and enantioselective catalysts, the system exhibits high regio- and enantioselectivity (ee up to 91%).

We report a selective dearomative cyclization strategy for the synthesis of 3,4-fused diazabicycles from 3-substituted pyridyl ynamides. The method combines a chemo-, regio-, and stereoselective carbometalation with a regioselective dearomatization, enabling access to a broad range of diazabicyclic scaffolds with varied ring sizes. The protocol accommodates alkyl and aryl Grignard reagents, tolerates diverse functional groups, and supports stereodivergent synthesis, offering a versatile platform for constructing complex fused -heterocycles with potential relevance to medicinal chemistry.
