Abstract
NEW MATERIAL:A compound expressed by formulaI(Y is H or halogen).
EXAMPLE: 9-Bromo-6, 7, 8-trihydroxy-1-hydroxymethyl-3-oxo-2-oxa-4-azabicyclo [3.3.1]nonane.
USE: An intermediate for valiolamine (having the α-glucosidase inhibitory action, and useful as medicines, food additives, etc.) expressed by formula II.
PROCESS: An N-substitution product of a valienamine expressed by formula III is reacted with a halogenating agent, e.g. a halogen or hypohalogenous acid, in a solvent, e.g. water, alcohol, DMF or benzene, usually at 0W70°C to give the compound expressed by formulaI(Y is halogen).
