REACTION Of GLYCOSYL ISOTHIOCYNATES WITH 3-INDOLYLAMINOMETHYL-KETONE HYDROCHLORIDE
摘要:
Reaction of glycosyl isothiocyanate la-c with 3-indolylaminomethylketone hydrochloride(2) yielded glycosylthiourea derivatives 3a-c. Cyclodehydration of 3a-c with acetic anhydride afforded 5-(indol-3-yl)-2-[N-per-O-acetyl-D-glycopyranosyl)amino]thiazoles 4a-c. Deacetylation of 4a-c gave 5-(indol-3-yl)-2-[N-(D-glycopyranosyl) amino] thiazoles 5a-c.
