Visible-light-induced photocatalytic decarboxylative alkynylations of carboxylic acids have been developed for the first time. The reaction features extremely mild conditions, broad substrate scope, and avoids additional oxidants. Importantly, a carbonylative alkynylation has also carried out in presence carbon monoxide (CO) under which affords valuable ynones high yields at room temperature.

The first copper-catalyzed asymmetric decarboxylative [4 + 1] cycloaddition of propargylic carbamates and sulfur ylides was successfully developed. This strategy led to a series chiral indolines with synthetically flexible alkyne groups in good yields high enantio- diastereoselectivities (up 99% yield, 98% ee, >95:5 dr). A possible mechanism stereoinduction mode copper–allenylidenes were proposed as the dipolar intermediate.

Catalytic asymmetric cycloadditions of reactive ketene intermediates provide new opportunities for the production chiral heterocyclic molecules. Though known over 100 years, ketenes still remain underexplored in field transition-metal (TM)-catalyzed because (1) ketenes, as highly electron-deficient species, are possibly unstable to low-valence TMs (i.e., decarbonylation or aggregation) and (2) conventional thermal synthesis from acyl chlorides amines may be incompatible with TM catalysis...

A novel visible-light-responsive chiral ligand has been developed by grafting a triplet state photosensitizer to bisoxazoline ligands. Complexation of this with Ni(acac)2 results in powerful catalyst for the asymmetric oxidation reaction β-ketoesters, which uses oxygen or air as green oxidant and visible light sunlight ideal driving force.
