摘要

Abstract: Benzylzinc reagents undergo palladium-catalyzed crosscoupling reactions with methylthio-substituted N-heterocycles in moderate to good yields. 2-(Methylthio) pyrimidines are particularly reactive substrates for this reaction. As a result, the regioselectivity of 2, 4-bis (methylthio) pyrimidines is opposite to that of their 2, 4-dichloropyrimidine analogues. This unusual cross-coupling reaction offers new flexibility in the regioselective synthesis of ...
