  Intramolecular Photoreaction of Thio-barbiturates with an Alkenyl or a Benzyl Group in Their N-Alkyl Side Chain. Regio-selective Synthesis of Ring-fused Pyrimidine Derivatives through Photocyclization of Mono- and Dithiobarbiturates

  摘要：

  Upon irradiation, thiobarbiturates with an alkenyl (4,5) or a benzyl (14,15,21) group in their N-alkyl side chain give bi- and tri-cyclic fused pyrimidine derivatives through regioselective [2+2] photocycloaddition or Norrish type II reaction, respectively.
