Highly stereoselective preparation of nitro olefins and nitro dienes by the addition-elimination of copper-zinc organometallics to β-alkylthio and β-phenylsulfonyl nitro olefins
The addition-elimination of copper-zinc organometallics RCu(CN)ZnX to (E)-1-nitro-2-phenylsulfonyl ethylene 2a gave highly functionalized pure (E) nitro olefins and stereoselectively (1E, 3E) and (1E, 3Z)-1-nitrodienes in excellent yields. β-Alkylthio nit

Multiple-stage Reactions with Participation of Latent α-Hetero-substituted Carbanions: Reaction of 2-Pyrrolecarbaldehyde with 1,2-Disubstituted Ethenes
The reaction of 1,2-bishetero-stabilized ethenes 2 with the anion of 2-pyrrolecarbaldehyde (1) yields the pyrrolizine derivatives 4 and 11 or pyrrolopyrimidopyrrolizines 8.A control of the reaction path and the yields by variation of
