Abstract
Nitromethane reacts via a diastereoselective double Michael addition with electrophilic alkenes activated by cyano and methoxycarbonyl groups [XC 6 H 4 CHC(CN)CO 2 Me] in the presence of catalytic amounts of piperidine under solvent-free conditions coupled with focused microwave irradiation to afford new, highly functionalized cyclohexenes; no cyclopropane formation is observed.Keywords
