Synthesis of (+)/(−) pentenomycins via Me2AlCl induced cascade reaction
摘要:
An efficient approach for the synthesis of (+) pentenomycin and (-) pentenomycin from D-ribose and D-mannose, respectively, is described using Tebbe olefination of lactones 9 and 7 followed by Me2AlCl induced disfavoured 5-(enol-endo)-exo-trig cyclization.

A new total synthesis of enantiomerically pure pentenomycin has been achieved by the intramolecular nitrone cycloaddition of the proper γ-unsaturated aldehyde, easily accessible from l-arabinose, followed by reductive NO bond cleavage and further oxidative deamination of the resulting aminocyclopentitol.

An efficient synthesis of enantiopure (-)- and (+)-pentenomycins are described by reductive iodo elimination and ring-closing metathesis (RCM), as the key steps. The first synthesis of the unnatural (+)-isomer is described. (C) 2003 Elsevier Science Ltd. All rights reserved.
