Wang, Eng-Chi,Hsu, Ming-Kun,Lin, Yu-Li,Huang, Keng-Shiang

, p. 1997 - 2010 (2002)

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.
