Highly Efficient and Versatile Synthesis of Isotopically Labelled 1-Deoxy-D-xylulose
摘要:
An efficient and versatile synthesis of 1-deoxy-[4,4-H-2(2)]-D-xylulose 1b (= 1-deoxy-[4,4-H-2(2)]-D-threopentulose) from dimethyl 2,3-O-isopropylidene-D-tartrate in 31% overall yield is described. The synthetic protocol allows a flexible adaptation to other labelling patterns and isotopes. Labelled 1-deoxy-xylulose is of high value as a metabolic probe in biosynthetic studies towards terpenoids and prenylated compounds following the Rohmer pathway.

An improved synthetic protocol towards 1-deoxy-[4,4-H-2(2)]-D-xylulose (1a) (= 1-deoxy-[4,4-H-2(2)]-D-threopentulose) from dimethyl 2,3-O-isopropylidene-o-tartrate (2) (44% overall yield) is described. The key-operation is a novel one-pot reductive alkylation of the protected halfester 3, by sequential treatment with superdeuteride(hydride) and methyl lithium, providing the protected 1-deoxy-D-xylulose (5) in high yield.
