一般說明

已经通过脉冲辐解法研究了乙醛二甲基缩醛的氧化降解动力学。在甲硅烷基三氟甲磺酸盐和胺碱存在下,它还与各种酮,酯,酰胺和硫酯进行加成反应。已经研究了路易斯酸介导的(S)-N-乙酰基-4-异丙基-1,3-噻唑烷-2-硫酮的钛烯醇化物与乙醛二甲基缩醛的反应。

應用

乙醛二甲基缩醛可用于制备硬脂醇的葡糖苷衍生物。它可以用作聚合物溶剂,将水溶性模型蛋白、牛血清白蛋白包裹成可生物降解的聚(D,L-乳酸)。

Glucoside derivatives of steganol analogous to the semisynthetic podophyllotoxin derivative, VP 16-213, were prepared. Glucosidation of steganol with 2, 3, 4, 6-tetra-O-benzylglucopyranose gave the alpha-anomer of the glucoside as the major product. Subsequent removal of the benzyl groups and reaction
