✦ Synopsis

Catalytic Asymmetric [4 + 1] Cycloaddition of Vinylallenes with Carbon Monoxide: Reversal of the Induced Chirality by the Choice of Metal.

-The synthetic utility of the asymmetric carbonylative [4 + 1] cycloaddition of vinylallenes is enhanced by the observation that either enantiomer of the cycloadducts can be obtained with moderate to good selectivity using a single enantiomer of a chiral diphosphine ligand by appropriate choice of the metal catalyst. -(MURAKAMI, MASAHIRO; ITAMI, KENICHIRO;
