An Alternative Route for Preparation of α-Methylphosphonyl-β, γ-Diphosphates of Thymidine Derivatives

Abstract
An alternative “one pot” synthesis of α-methylphosphonyl-β, γ-diphosphates of thymidine and 3′-azidothymidine is proposed. p-Toluene-sulphonic acid was used as desililating agent for triphosphate analogues.
