✦ Synopsis

We wish to report a catalytic synthetic method for the preparation of heterocyclic aromatic addition compounds in homogeneous media. We have found it possible to alkenylate a large number of heterocyclic compounds in significant quantities. The reaction of a conjugated diene with a compound of the typetAr-CH,(Ar = 1 0 , 8,8 , ($ 1 pro~ces the addition products in good yields. The following scheme indicates the two monoaddition and one diaddition products obtained when isoprene is the olefin used:

## Abstract The purpose of this study is to point out the synthetic utility of a new class of Michael acceptors (nitrodienes and nitroenynes). The highly enantioselective organocatalytic Michael addition of carbonyl compounds to these functionalized nitroolefins has been carried out in the presence
