- 中文摘要: New syntheses of 4-alkoxy-3-methoxy-5H-benzocycloheptenes and 2-alkoxy-3-methoxy-5H-benzocycloheptenes were studied. Based on Claisen rearrangement, O-alkylation, nucleophilic addition of allyl magnesium bromide, ring-closing metathesis, and dehydration, a series of new 4-alkoxy-3-methoxy-5H-benzocycloheptenes and 2-alkoxy-3-methoxy-5H-benzocycloheptenes were respectively synthesized from isovanillin in good overall yields.
