The reactivities of the lauryl glycosides for glycosidation by means of TMSOTf as a convenient promoter were investigated, and the lauryl thioglycoside showed satisfactory activities. Further transformation of the lauryl glycoside was also attempted to give a 5-azide analogue 14 of the sialic acid, which was also reacted with a secondary alcohol in the presence of TMSOTf to give known glycoside 15 in high yield., text, application/pdf}, pages = {9383--9386}, title = {Synthesis of a useful lauryl thioglycoside of sialic acid and its application}, volume = {45}, year = {2004}, yomi = {マツオカ, コウジ and テルヌマ, ダイヨウ and ハタノ, ケン} }
