Abstract:
An object of the present invention is to provide a novel compound useful for manufacturing salacinol, a method for manufacturing the compound, a method for manufacturing salacinol, methods for protecting and deprotecting a diol group, and a protective agent for a diol group. A compound represented by Formula (1) is a compound useful for manufacturing salacinol. (In the formula, each of R 1a  and R 1b  is a hydrogen atom or a hydroxy protective group; R 2  is a hydroxy group or the like; and R 3  is a hydroxy group or the like.)

Claim (Index 5):
A method for protecting a 1,2-diol group or a 1,3-diol group, comprising manufacturing a compound represented by Formula (21) by reacting a 1,2-diol group or a 1,3-diol group of a compound represented by Formula (20) with a compound represented by Formula (9) in the presence of a base,\n (in the formula, Y 1  is a C 2-3  alkylene group which may be substituted), (in the formula, each of R 1a  and R 1b  are the same as or different from each other and each represent a hydrogen atom or a carboxy protective group; and R 6  is a C 1-6  alkyl group which may be substituted), and (in the formula, each of R 1a , R 1b , and Y 1  has the same definition as described above).
