N-tosyl-2-pyrrolidone 5 were condensed with cyano compounds in the presence of triflic anhydride (Tf2O) to yield heteroarylpyrimidines. 2,4-Difunctionalized pyrimidines were obtained by reaction of the corresponding 2,4-bis(methylsulfonyl)pyrimidines with nucleophiles.
在三氟甲酸酐(Tf 2 O)存在下,将N-甲苯磺酰基-2-和-3-乙酰基吡咯1或N-甲苯磺酰基-2-吡咯烷酮5与氰基化合物缩合,得到杂芳基嘧啶。通过使相应的2,4-双(甲基磺酰基)嘧啶与亲核试剂反应获得2,4-双官能化的嘧啶。
