从薄荷酮出发经肟化反应,贝克曼重排反应,以及酰基化反应,合成了一系列标题化合物,其中N-乙酰基取代的产物的产率高达94.8%。通过^1HNMR和^13CNMR对各步产物进行了表征。
A series of N-substituted ( 4R, 7S ) -7-isopropyl-4- methy]azepan-2-one was synthesized from menthone via oxi- mation,beckmann rearrangement and acyiation. The yield of the acetylation was up to 94.8%. The structures of the products were confirmed by ^1HNMR and ^13 CNMR.
