Short approach to functionalised homochiral piperidinones
摘要:
The preparation of homochiral lactam 4 in 5 steps from (S)-lysine is described. Conversion to bicyclic O,N-acetal 5 provides a useful template for further elaboration to highly substituted piperidinones with excellent diastereoselectivity.
