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...
