<p><P>PROBLEM TO BE SOLVED: To provide a method for introducing site-selectively different protective groups to various hydroxy groups of an alkylβ-D-(thio)glucopyranoside derivative. <P>SOLUTION: The method for producing a compound represented by general formula [7] (wherein R<SP>1</SP>is an alkyl group or an aralkyl group; R<SP>2</SP>is an acyl group; and X is O or S) comprises reacting a compound represented by general formula [4] with TBDPSX<SB>1</SB>(wherein X<SB>1</SB>is a halogen), then reacting the resultant product with di-tert-butyl dicarbonate in the presence of a pyridylpyrrolidine catalyst and reacting the resultant substance with BOMX1. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
