Synthesis of the novel antibacterial 6,8-dihydroxy-7-propyl-9H-pyrrolo[1,2-b][1,3]-benzoxazin-9-one
摘要:
The total synthesis of 6,8-dihydroxy-7-propyl-9H-pyrrolo[ 1,2-b][1,3]benzoxazin-9-one, a novel antibacterial agent, is described. The key step in the synthesis is achieved via an oxidative cyclization of a phenol to the 2-position of a pyrrole using stoichiometric Pd(OAc)(2). This provides a straightforward approach to the tricyclic structure of this prevously unreported template and future derivatives. (C) 2000 Elsevier Science Ltd. All rights reserved.
