Activation of Methylphosphonates and Their Thio- and Seleno Congeners with 1,3,5-Triazinyl Morpholinium Salts. Selenono-Selenolo Isomerization
摘要:
The stereospecific activation of nucleoside 3'-O-methylphosphonoselenoates (1) with N-methyl-N-4,6-dimethoxy-1,3,5-triazinyl-yl morpholinium chloride resulted in formation of both O-activated (5) and Se-activated (6) 1,3,5-triazin-yl esters.[GRAPHICS]
