alcohols, acetonides, and α-alkoxy ketones is achieved by using molybdenum(VI) dichloride dioxide (MoO 2 Cl 2 ) as a catalyst. Alcohol, aldehyde, oxime, tosyl, and TERT-butyldimethylsilyl functional groups are tolerated during the methanolysis and acetonidation of the functionalized epoxides. No polymerization product is observed with any of the epoxides. Direct conversion of epoxides devoid of sensitive
通过使用二氯化钼 (VI) 二氧化 (MoO 2 Cl 2 ) 作为催化剂,可以将环氧化物转化为 β-烷氧基醇、丙酮化物和 α-烷氧基酮。在官能化环氧化物的甲醇分解和丙酮化过程中,醇、醛、肟、甲苯磺酰基和叔丁基二甲基甲硅烷基官能团是可耐受的。没有观察到任何环氧化物的聚合产物。通过使用 MoO 2 Cl 2 /Oxone 系统,可以在一个步骤中将不含敏感官能团的环氧化物直接转化为相应的 α-甲氧基酮。
