✦ Synopsis

The allylindation of cyclopropenes (I) is found to depend remarkably on the nature of the substituent at the α-carbon. Thus, a hydroxymethyl and carboxyl group direct to the cis products (III) based on intramolecular chelation, whereas acetoxymethyl and ester groups direct to trans products (IV) due to steric interaction with the incoming allylindium reagent (II). -(ARAKI, S.;
