primary, secondary, and tertiary alcohols was carried out with up to 98% isolated yield. Additionally, double deoxygenation was achieved when the present method was applied to α,β-dihydroxy ketones to access the corresponding enones in a single step.
使用甲硅烷基锂试剂和乙酸酐开发了一种可靠的 α-羟基酮一步直接脱氧方法。该方法不含金属催化剂,并且不需要在去除羟基之前对其进行预官能化。对不同的伯醇、仲醇和叔醇进行脱氧,分离收率高达 98%。此外,当本方法应用于α,β-二羟基酮以一步获得相应的烯酮时,实现了双重脱氧。
