Application of the grubbs ring-closing metathesis for the construction of a macrocyclic ansa-bridge. Synthesis of the tricyclic core of roseophilin
摘要:
Metalation/alkylation of the pyrrole-fused 10 pi anion 15 regiospecifically yields the beta-alkylated ketones 16,17, Conversion of 17 to diene 24 followed by Grubbs ring-closing metathesis provides 29 which is transformed to the roseophilin tricyclic core structure 5. (C) 1997 Elsevier Science Ltd.
