Synthesis of all four isomers of (E)-4,5-dihydroxydec-2-enal using osmium-catalysed asymmetric dihydroxylation
摘要:
The enantioselective synthesis of the four possible isomers of (E)-4,5-dihydroxydec-2-enal, a cytotoxic product formed in peroxidised liver microsomal lipids, is accomplished via a Sharpless AD reaction alone or associated as appropriate with a regioselective epimerisation of one of the introduced hydroxy groups.

Using (2E)-4,4-dimethoxy-2-butenal as starting compound, methods were developed for synthesis of (2E,4E)- and (2E,4Z)-dimethoxyalkadienes. Deacetalization of the latter gives with high yield the corresponding dienals which are naturally occurring compounds and also synthons for preparation of conjugated dienes as key compounds for building up other natural products.
