The enantioselective deprotonation of the 8-oxabicyclo[3.2. l]octan-3-one with chiral lithium amides 5 and 6, in the presence of LiC1, gave the chiral lithium enolates which were in turn reacted with methyl cyanoformate. The resulting chiral [3-keto esters were reduced with sodium amalgam to afford

New methodology for the synthesis of enantiopure 3-aza-6,8-dioxa-bicyclo[3.2.1]octane-carboxylic acids belonging to 7-endo-BTAa sub-class of g/d amino acids is described. The novelty is the use of 2,3-O-isopropylidene-erythrose instead of meso-tartaric acid derivative, thus allowing us to perform an
