Abstract

The MeOPEG-supported azide 2 was reacted in the presence of a number of alkynyl dipolarophiles. The corresponding 1-MeOPEG-supported-1,2,3-triazoles were obtained in nearly quantitative yields. Acidic hydrolysis of the cycloadducts 5b and 6b caused the removal of the MeOPEG pendant giving 4-methoxycarbonyl-1,2,3-triazole 9 and 5-methoxycarbonyl-1,2,3-triazole 10, respectively.
