摘要

Abstract A simple and high-yield synthesis of biologically significant 2′-deoxy-6- thioguanosine (11), ara-6-thioguanine (16) and araG (17) has been accomplished employing the Stereospecific sodium salt glycosylation method. Glycosylation of the sodium salt of 6-chloro-and 2-amino-6-chloropurine (1 and 2, respectively) with 1-chloro-2-deoxy-3, 5-di-O-(p-toluoyl)-α-D-erythro-pentofuranose (3) gave the corresponding N-9 substituted ...
