CONVERSION OF D-MANNOSE INTO 1,5-ANHYDRO-D-ALLITOL-4,6-ACETONIDE; UNUSUAL INTRAMOLECULAR EPOXY ALCOHOL OPENING IN BASE

Treatment of 3-tosyl-D-mannose-4,6-acetonide 9 with sodium borohydride affords an epoxy alcohol 11 which on treatment with base gives 1,5-anhydro-D-allitol-4,6-acetonide 15 by a 6-endo opening of the rearranged epoxy alcohol 13 rather than the product of
