  Synthesis and cycloadditions of 9H-furo[3,4-b][1]benzo(thio)pyran-9-ones: furan ring formation by a novel hydrolytically induced cycloreversion

  摘要：

  C-2 lithiation of acetals 2 followed by trapping with aldehydes gives 3. Subsequent unmasking of the acetal function provides furobenzo(thio)pyrans 4, cycloadditions of which have been investigated. (C) 2002 Elsevier Science Ltd. All rights reserved.
