Diastereoselective additions of alkyl-, alkenyl-, aryl- and allylcuprates to chiral unsaturated imides: Diastereoselective additions of alkyl-, alkenyl-, aryl- and allylcuprates to chiral unsaturated imides. Melnyk, Oleg; Stephan, Elie; Pourcelot, Guy; Cresson, Pierre (Lab. Synth. Org., ENSCP, Paris 75231, Fr.). Tetrahedron, 48(5), 841-50 (French) 1992. CODEN: TETRAB. ISSN: 0040-4020. 18802-94-3 and 1730-92-3 are cas registry numbers of chemicals which are used as reagents here. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Some diastereoselective conjugate addns. of cuprates to chiral unsatd. imides I (R = Me, Et, Pr, Ph, 4-MeC6H4) show an impressive stereoselectivity. The chiral (internal auxiliary dependent) group is easily cleaved and recycled. The steric course of these reactions seems quite general and its development synthetically promising. .
