A process for the separation and/or purification of oligo- and polyhydroxy compounds by introducing and subsequently eliminating protective groups, wherein oligo- and polyhydroxy compounds are reacted with bis(ethyl-pivaloyloxy)-diboroxane or ethylboroxine, optionally in inert solvents, the resulting O-ethylboranodiyl derivatives of the hydroxy compounds are separated off and the O-ethylboranodiyl protective groups are eliminated by alcoholic compounds, for example methanol or glycol.
一种通过引入和随后消除保护基团来分离和/或纯化寡聚和聚羟基化合物的过程,其中将寡聚和聚羟基化合物与双(乙基-异戊酰氧基)二
