(3-Hydroxy-3-methylbutyn-1-yl)cycloalkan-1-ols were prepared by the action of (2-lithiooxy-2methylbutyn-3-yl)lithium on cyclopentanone, cyclohexanone, cycloheptanone, and cyclododecanone. The products react with acetonitrile under Ritter reaction conditions. Therewith, in the presence of 8 g-equiv of sulfuric acid, a 2: 1 mixture of 1-acetylamino-1-(2-acetylamino-2-methylbutyn-3-yl)cycloalkanes and 1-acetylamino-1-(3-acetylamino-3-methylbutyryl)cycloalkanes is formed, whereas in the presence of 2 g-equiv of the acid, a mixture of 1-acetylamino-1-(2-acetylamino-2-methylbutyn-3-yl)cycloalkanes and 1-acetylanuno-l(3-methyl-2-butenoyl)cycloalkanes in the same ratio.
(3-羟基-3-甲基丁炔-1-基)环烷-1-醇是通过(2-锂氧基-2-甲基丁炔-3-基)锂与环戊酮、环己酮、环庚酮和环十二酮反应制备的。产物与氰化物在Ritter反应条件下反应。其中,当存在8当量硫酸时,生成1-乙酰氨基-1-(2-乙酰氨基-2-甲基丁炔-3-基)环烷烃与1-乙酰氨基-1-(3-乙酰氨基-3-甲基丁酰基)环烷烃的2:1混合物;而当存在2当量硫酸时,生成1-乙酰氨基-1-(2-乙酰氨基-2-甲基丁炔-3-基)环烷烃与1-乙酰氨基-1-(3-甲基-2-丁烯酰基)环烷烃的相同比例混合物。
