Allylic‐Type Diindium Reagents. Reactivity Toward Electrophiles and Cascade Coupling Reactions with Imines.

Abstract

Allylic-Type Diindium Reagents. Reactivity Toward Electrophiles and CascadeCoupling Reactions with Imines. -The reaction of the allylic-type diindium reagents generated from the halides (I) and (V) with electrophiles is studied. They show different behavior toward water and aldehydes. For example, the diindium reagent resulting from (V) smoothly reacts with two molecules of aldehydes to afford diols, whereas the diindium reagent from (I) only reacts with one molecule of aldehyde. The cascade coupling with imines and allyl halides provides a versatile route to linear homoallylic amines. -(HIRASHITA*, T.; HAYASHI, Y.; MITSUI, K.; ARAKI, S.;
