Novel synthesis of CP-734432, an EP4 agonist, using Sharpless asymmetric dihydroxylation
摘要:
A novel and efficient asymmetric route to CP-734432, a lactam analog of PGE2, that shows selective agonism against the EP4 receptor subtype, is reported herein. The key steps include a Heck coupling to introduce the aryl ring at C-16 and a highly diastereoselective Sharpless asymmetric dihydroxylation to set the C-15 center. (C) 2009 Elsevier Ltd.
