Asymmetric synthesis of homochiral Baylis–Hillman products employing (R)-N-methyl-N-α-methylbenzyl amide
摘要:
The conjugate addition of (R)-N-methyl-N-alpha-methylbenzyl amide to tert-butyl cinnamate followed by an asymmetric aldol reaction and subsequent N-oxidation/Cope elimination affords beta-substituted homochiral Baylis-Hillman products in good yield.
