Treatment of easily obtainable 1-alkylamino-1,3,6-trideoxyhexitols with hydrogen fluoride in the presence of formic acid gives the corresponding C-5 inverted 2,5-anhydrides in high yields. The synthesis of allo-muscarine and its N-benzyl analog from galactono-1,4-lactone is reported in 30 and 41% overall yield, respectively.
