资源简介：
An expedient construction of the 5–6–7
tricyclic
core of daphnicyclidin-type alkaloids is described. The synthetically
challenging cycloheptanone C ring was constructed via a Tiffeneau–Demjanov
ring enlargement reaction from a 5–6–6 tricyclic precursor
commonly found in calyciphylline A-type alkaloids. Other key transformations
included Davis oxidation, 1,2-addition, oxidation, and dehydration
to elaborate the essential cyclcohept-2-enone motif.
