6-Acetyl-2-isopropenyl-5-methoxy-2,3-dihydrobenzofuran was prepared from 2-isopropenyl-5-methoxy-2,3-dihydrobenzofuran via formylation, Grignard methylation, and oxidation. It was then converted to two racemic dihydrobenzofuran derivatives obtained from Baccharis conferta.
6- 乙酰基-2-异丙烯基-5-甲氧基-2,3-二氢苯并呋喃是由 2-异丙烯基-5-甲氧基-2,3-二氢苯并呋喃通过甲酰化、格氏甲基化和氧化反应制备而成。然后将其转化为两种外消旋二氢苯并呋喃衍生物,这两种衍生物均取自 Baccharis conferta。
