  Total synthesis of pulverolide: revision of its structure

  摘要：

  A flexible and practical strategy toward the synthesis of rare 2H-furo[3,2-b]benzopyran-2-one skeleton has been developed. With a microwave-assisted cyclization-dehydration as the key transformation, the first total synthesis of pulverolide has been completed in 10 steps with 9% overall yield, leading to the revision of its proposed structure.

  2-Allyl-3-alkoxy-4-methoxyphenol, prepared from isovanillin via the Claisen rearrangement, O-alkylation and Baeyer-Villiger oxidation, were chloroethylated by two-phase reaction to furnish 1-allyl-3-alkoxy-(2-chloroethoxy)-4-methoxy- benzenes. The given compounds were treated with potassium tert-butoxide to undergo the isomerization of O-allyl group and dehydrochlorination of 2-chloroethoxy group to efficiently

  日期：——

  Based on Claisen rearrangement, Baeyer-Villiger oxidation, and ring-closing metathesis (RCM), a series of substituted 2,5-dihydrobenzo[b]oxepines were synthesized from isovanillin in good over-all yields. Other appropriate substituted 2,5-dihydrobenzo[b]oxepines prepared from corresponding phenol derivatives were also described.
