Double-Mannich Annulation of Cyclic Ketones Using N,N-Bis(ethoxymethyl)alkylamine Reagents
摘要:
N, N-Bis(ethoxymethyl) alkylamines function as effective reagents in the double-Mannich annulation of cyclic ketone substrates, providing efficient access to a series of azabicyclic ketones. These ring systems are a useful scaffold for the four-step synthesis of novel constrained homocholine analogues.
