COMPOUND USEFUL FOR MANUFACTURING SALACINOL, METHOD FOR MANUFACTURING THE COMPOUND, METHOD FOR MANUFACTURING SALACINOL, METHODS FOR PROTECTING AND DEPROTECTING DIOL GROUP, AND PROTECTIVE AGENT FOR DIOL GROUP

摘要

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 R1a and R1b is a hydrogen atom or a hydroxy protective group; R2 is a hydroxy group or the like; and R3 is a hydroxy group or the like.)
