Synthesis of Chiral 3-Substituted 2,4(1H,3H)-Quinazolinediones
摘要:
2-Carbomethoxyphenyl isocyanate and 6-nitro-2-carbomethoxyphenyl isocyanate were generated in situ from half-esters, and then converted into the corresponding quinazolinediones using alpha-amino acids. This useful annelation process was found to be a general method for the formation of various chiral 3-substituted quinazolinediones.
