with excess of [2H6]-acetic anhydride is described. It has shown that 3-hydroxy-3-methylpentane-1,5-dioic acid anhydride (2), previously described by Scott and Shishido 1 as an intermediate in their synthesis of [3′-13C]mevalonolactone, is formed only transiently, along with 3-acetoxy-3-methylpentane-1,5-dioic acid (6). Both intermediates eventually give 3-acetoxy-3-methylpentane-1,5-dioic acid anhydride
描述了3-羟基-3-甲基戊烷-1,5-二酸(5)与过量的[ 2 H 6 ]-乙酸酐反应的NMR研究。已经显示,Scott和Shishido 1先前描述的3-羟基-3-甲基戊烷-1,5-二酸酐(2)只是它们的[3'- 13 C]甲羟戊内酯合成中的中间体而已,以及3-乙酰氧基-3-甲基戊烷-1,5-二甲酸(6)。两种中间体最终均产生3-乙酰氧基-3-甲基戊烷-1,5-二甲酸酐(3)。

The macrocyclic trichothecene triester 3′-hydroxy-2′-deoxy-2",3",4",5"-tetrahydroverrucarin A (37), has been synthesized starting from the sesquiterpene alcohol verrucarol (3), adipic acid and a derivative of mevalonic acid (14). The latter has been prepared from 4-(tetrahydro-2-pyranyloxy)-2-butanone (9).
