Photoredox-catalyzed Divergent Defluorofunctionalizations of gem-difluoroarylalkenes with Nucleophiles to Access α-arylated Carboxylic Acids and its Derivatives.

The construction of α-arylated carboxylic acids and its derivatives has predominantly relied on transition-metal-catalysis, leading to potential metal contamination. Herein, we report a transition-metal-free photocatalytic protocol for the defluorinative carboxylation, esterification, and amidation of gem-difluoroarylalkenes with diverse nucleophiles to access a variety of α-arylated carboxylic acids, esters, and amides. The strategy features operational simplicity, mild reaction conditions, and excellent substrate compatibility, providing efficient access to pharmaceutically relevant architectures.

Modular assembly of amines and diborons with photocatalysis enabled halogen atom transfer of organohalides for C(sp)-C(sp) bond formation.

In the past few years, the direct activation of organohalides by ligated boryl radicals has emerged as a potential synthetic tool for cross-coupling reactions. In most existing methods, ligated boryl radicals are accessed from NHC-boranes or amine-boranes. In this work, we report a new photocatalytic platform by modular assembly of readily available amines and diboron esters to access a library of ligated boryl radicals for reaction screening, thus enabling the cross-coupling of organohalides and alkenes including both activated and unactivated ones for C(sp)-C(sp) bond formation by using the assembly of DABCO A1 and BNepB1.

Thiyl Radical Trapped by Cobalt Catalysis: An Approach to Markovnikov Thiol-Ene Reaction.

In the presence of a thiyl radical species, the catalytic Markovnikov thiol-ene reaction is challenging because it prefers to proceed via a radical pathway, thereby leading to -Markovnikov selectivity. In this work, a rare example of thiyl radical engaged in Markovnikov thiol-ene reaction enabled by cobalt catalysis is reported. This protocol features the avoidance of unique oxidants, exclusive regioselectivity, and broad substrate scope.

Targeting scleral remodeling and myopia development in form deprivation myopia through inhibition of EFEMP1 expression.
