Uncatalyzed conjugate additions of diorganozincs in N-methylpyrrolidinone
摘要:
Diorganozincs efficiently add to enones, unsaturated nitriles and nitroolefins in a mixture of THF and NMP furnishing the corresponding Michael adducts in good to excellent yields. Copyright (C) 1996 Elsevier Science Ltd
pyrrolidine gave a dipeptide-connected amidomonophosphane ligand for the highly efficient, copper-catalyzed asymmetric conjugateadditionreaction of organozinc reagents with cycloalkenones, giving 3-alkylated cycloalkanones in high enantioselectivity of up to 98 % ee. A model that predicts the stereochemistry of the reaction is discussed.
