The utility of 2,3-dialkoxybutan-1,3-dienes as reagents for the protection of vicinal diols and α-hydroxy acids as their corresponding 1,2-diacetals is demonstrated together with their later deprotection under mild reaction conditions.
2,3-二烷氧基丁-1,3-二烯作为保护邻位二醇和α-羟基酸的试剂,其转换为相应的1,2-
二乙酰基保护形式的实用性得到证实,并展示了在温和反应条件下的后续去保护过程。
