Disclosed is a process for the production of a 4-(2-hydroxyalkyl)-1,2-benzenediol, comprising the steps of (a) providing protected 1,2-benzenediol having the 1,2-hydroxyl groups protected, (b) halogenating the protected 1,2-benzenediol to obtain a protected 4-halo-1,2-benzenediol having the 1,2-hydroxyl groups protected, (c) reacting, in the presence of a metal or organometallic compound, the protected 4-halo-1,2-benzenediol to protected 4-(2-hydroxyalkyl)-1,2-benzenediol having the 1,2-hydroxyl groups protected, and (d) deprotecting the protected 4-(2-hydroxyalkyl)-1,2-benzenediol to obtain the 4-(2-hydroxyalkyl)-1,2-benzenediol. Also disclosed is the use of 1,2-benzenediol for the production of hydroxytyrosol.
揭示了一种生产4-(2-羟基烷基)-1,2-苯二酚的方法,包括以下步骤:(a)提供具有1,2-羟基受保护的1,2-苯二酚,(b)对受保护的1,2-苯二酚进行卤代反应,得到具有1,2-羟基受保护的受保护的4-卤代-1,2-苯二酚,(c)在金属或有机金属化合物的存在下,将受保护的4-卤代-1,2-苯二酚与受保护的4-(2-羟基烷基)-1,2-苯二酚反应,得到具有1,2-羟基受保护的受保护的4-(2-羟基烷基)-1,2-苯二酚,(d)脱保护受保护的4-(2-羟基烷基)-1,2-苯二酚,得到4-(2-羟基烷基)-1,2-苯二酚。还揭示了利用1,2-苯二酚生产羟基酪醇的用途。
