We herein report the hitherto unknown synthesis of 3-deazacarbovir and its adenosine analogue. The major highlight in the synthesis of adenosine analogs is to use 6-N,N-diboc protected 3-deazapurines 9 and 11 for regioselective Mitsunobu coupling as well as unexplored palladium catalyzed coupling with these substrates. Synthesis of 3-deazacarbovir 1 has been accomplished by the regioselective palladium
