一般描述
2,2-二甲氧基丙烷（DMP）是通常用作生产2-甲氧基丙烯（MPP）的前体的有机结构单元。离子液体中的DMP降解研究表明，由于隧道效应，MPP和2-乙氧基丙烯（EPP）以相同的比例形成。据报道，可基于从头计算和基质分离红外光谱对DMP进行构象分析。DMP与水反应生成甲醇和丙酮。该反应被应用于气-液色谱法定量测定天然产物中的水。酸化DMP被用于生物样品的脱水。
应用
用于制备1,2-二醇作为丙酮化合物的试剂。

Preparation of partially protected brassinosteroids is achieved through the reaction of the source material (24-epicastasterone and 24-epibrassinolide) with diol-specific reagents (2,2-dimethoxypropane and methylboronic acid). The obtained products were shown to be useful synthetic intermediates for further preparation of minor representatives
