  摘要：

  An efficient synthetic route to 3-(phenylsulfonyl)phthalides possessing a beta -C-olivoside was developed by exploiting the regioselective [2+2] cycloaddition of benzyne with ketene silyl acetal. The compounds are useful in the total synthesis of the angucyclines, including aquayamycin. (C) 2000 Elsevier Science Ltd. All rights reserved.
