An enantioselective synthesis of the bicyclic core of the marine natural product awajanomycin
摘要:
A concise stereoselective synthesis of the N-benzylated bicyclic core of the marine natural product awajanomycin is described starting with naturally Occurring L-alanine. Key steps in the synthesis include a ring-closing metathesis to establish a delta-lactam ring followed by a stereoselective hydroxylation to instal the quaternary centre. (C) 2010 Elsevier Ltd.
