A Direct Entry to Carbasugars: Asymmetric Synthesis of 1-epi-(+)-MK7607
Publication History
Publication Date:
08 December 2006 (online)
Abstract
A short and flexible synthesis of 5a-carbasugars is presented. The combination of a proline-catalyzed aldol reaction and a ring-closing metathesis affords 1-epi-(+)-MK7607 in seven steps with an overall yield of 23%.
Key words
carbasugars - organocatalysis - asymmetric synthesis - aldol reaction - ring-closing metathesis
