Under the conditions of the Wharton reaction, the (±)-epoxy-γ-dihydroionones 2 and 3 are transformed into the allylic alcohols 4–10. γ-Damascols 4, 5 and 8 were oxidised to cis- and trans-γ-damascone 12 and 13. Alternatively, dehydro-γ-damascol 18 was obtained by Wittig rearrangement of butinyl ether 17, and converted into damascones 12 and 13.
在沃顿反应的条件下,(±)-环氧-γ-
二氢紫罗兰酮2和3转化为烯丙基醇4-10。γ-大马士革4、5和8被氧化为顺式和反式-γ-大马康烯12和13。备选地,通过
丁烯基醚17的Wittig重排获得脱氢-γ-大马
酚18,并将其转化为大马康糖烯12和13。
