Proacacipetalin and acacipetalin
Abstract
The long-known cyanogenic glucoside acacipetalin, confirmed to be 2-(β-D-glucopyranosyloxy)-3-methylbut-2-enenitrile, can be produced from a natural β-D-glucopyranoside of 2-hydroxy-3-methylbut-3-enenitrile, which is distinguished from its epimer and named proacacipetalin.
