Abstract Two new efficient routes for the synthesis of pentaerythritol monobenzyl ether are described. In one route, the known mono‐O‐benzylidenepentaerythritol (5) is selectively benzylated via its dibutylstannylene acetal and then the benzylidene acetal is hydrolized. In the other route, compound 5 is reduced directly to the monobenzyl ether using EtAlCl2‐Et3SiH.
摘要 描述了合成季戊四醇单苄基醚的两条有效路线。在一种途径中,已知的单-O-亚苄基季戊四醇 (5) 通过其二丁基亚锡乙缩醛选择性地苄基化,然后将亚苄基乙缩醛水解。在另一条路线中,使用 EtAlCl2-Et3SiH 将化合物 5 直接还原为单苄基醚。
