More recently, a facile synthesis of 126 and pseudo-a-L-glucopyranose (137) has been described [32], When the bromolactone 38 was heated with glacial acetic containing hydrogen bromide and subsequently acetylated, DL-(l,3,5/2,4)-2,3-diacetoxy-4,5-dibromocyclohexane-l-carboxylic acid (130) was obtained [31], Resolution of 130 with optically active a-methylbenzylamines provided the enantiomer (131), m.p. 

Analogous reactions from 132 gave pseudo-a-L-glucopyranose pentaacetate (136), [a]p° —56° (chloroform), which was converted into pseudo-a-L-glucopyranose 137, [a]31 —67° (methanol), on hydrolysis [32] (Scheme 23).
