摘要：

The spirocycle is a key structure found in many bioactive compounds. From the cytotoxic and spirocyclic natural product, spiromamakone A (1) and its analogues, a more synthetically accessible spiroacetal template 4 was designed based on structural similarity analysis. A total of 50 compounds were rapidly synthesized in only one or two synthetic steps from the starting compound, and their cytotoxicity was evaluated. As a result, (+/-)-(2R*,5R*)-2-(4-iodophenyl)-7-chloro-1,4-dioxa-spiro[4.5]deca-6,9-dien-8-one (7d-II) was discovered and found to be fifteen-fold more cytotoxic than 1. The easily accessible spiroacetal 7d-II appeared to act in a manner similar to the highly oxidized natural product, spiromamakone A (1). (C) 2013 Elsevier Masson SAS. All rights reserved.
