been developed using the diastereocontrolled addition of organometallics to a (R)-cyclohexylideneglyceraldehyde-derived ketone as the key steps. The addition of vinylmagnesium bromide to the ketone gave a 1:1 diastereomeric mixture of separable tertiary alcohols, which were converted to the target erythri- and threitols. On the other hand, the reaction of a dithianyl anion with the ketone gave only the
使用非金属控制地将有机金属化合物添加到(R)-环己叉基甘油醛衍生的酮中作为关键步骤,已经开发了标题化合物的两种简短简便的合成方法。将乙烯基溴化镁添加到酮中,得到可分离的叔醇的1:1非对映异构体混合物,将其转化为目标赤藓糖醇和苏糖醇。另一方面,二噻吩基阴离子与酮的反应仅产生叔醇的单一立体异构体,其被转化为赤藓糖醇。
