Enantioselective synthesis of 2,2-dialkyltetrahydropyran-3-ones via the asymmetric Michael addition reaction using chiral imines
摘要:
Addition of chiral imine 8 derived from 2-methyltetrahydropyran-3-one 7 and R-(+)-1-phenylethylamine, to methyl acrylate led to adduct (S)-9 with a good yield and an excellent stereoselectivity.
