The title compound was synthesized in three steps from ethoxycarbonylformamide oxime (5) and 3,4,6-tri-O-acetyl-2,5-anhydroallonyl chloride (4b) in 62% overall yield. An acid catalyzed de-esterification was required to prevent a facile base catalyzed elimination reaction.
分三步从乙氧基羰基甲酰胺肟(5)和3,4,6-三-O-乙酰基-2,5-脱水丙二酰氯(4b)合成标题化合物,总收率为62%。需要酸催化的脱酯作用以防止碱催化的容易的消除反应。
