Facile nucleophilic displacement on a 4-triazolylpyrimidine deoxynucleoside: single-step synthesis of N-acylated 5-methyldeoxycytidines
Abstract
A 4-triazolyl substituted pyrimidine nucleoside undergoes nucleophilic displacement with the sodium salts of amides and thiols at room temperature in 1,4-dioxane exclusively at the 4-position to provide a simple and efficient preparation of 4-N-acylated and 4-thiolated analogues, respectively.
