A transition metal-free cross-dehydrogenative coupling of coumarins with acetonitrile or acetone has been established. A series of coumarins were subjected to reaction with acetonitrile or acetone in the presence of tert-butyl benzoperoxoate and potassium fluoride for direct synthesis of 3-cyanomethyl (or acetomethyl) coumarins. The method exhibits good functional group tolerance, and desired products were obtained in moderate to good yields. Meanwhile, a radical pathway was proposed to describe the cross-dehydrogenative coupling of coumarins with acetonitrile.

The synthesis of cyano-containing ring-fused quinazolin-4(3H)-one derivatives was developed under metal-free conditions. This synthesis involves radical C(sp3)-H functionalization of alkyl nitriles, and cascade radical addition/cyclization with N-alkylated quinazolinones to deliver cyanoalkylated pyrrolo- and piperidino-quinazolin-4(3H)-ones in moderate to excellent yields. Moreover, a derivative of the natural product leucomidine C was synthesized conveniently using the current protocol.

, p. 89 - 94 (2007/10/02)
2,4,6-Trisubstituted symm-triazines containing sterically-hindered phenol fragments were synthesized by the cyclotrimerization of ethyl iminoesters. 2,4,6-Trimercapto-symm-triazine derivatives containing shielded phenol residues may be formed by the cyclo
