3,4,6-tetra- O-pivaloyl-β- D-glucopyranosyl)thiourea with a variety of carbonyl compounds bearing an α-H in the presence of [hydroxy(tosyloxy)iodo]benzene (HTIB) and triethylamine, has been developed. The methodology has advantages such as avoiding the use of lachrymatory and toxic bromine, simplicity of procedure, mild reaction conditions, and high yields.
一种用于制备噻唑-2(3 H)-亚胺连接的糖缀合物的新型便捷合成方法,包括 1-苯甲酰-3-(2,3,4,6-四-O-新戊酰-β)的环化- 在[羟基(甲苯磺酰氧基)碘]苯(HTIB)和三乙胺存在下,D-吡喃葡萄糖基)硫脲与多种带有α-H的羰基化合物已被开发出来。该方法具有避免使用催泪和有毒溴、程序简单、反应条件温和、收率高等优点。
