  Preparation of a Useful Synthetic Precursor, 2-Substituted 4(3H)-Quinazolinone: Directed Lithiation and N3-Deprotection of 3-t-Butoxycarbonyl-4(3H)-quinazolinone

  摘要：

  Directed lithiation of 3-t-butoxycarbonyl-4(3H)-quinazolinone using LDA was accomplished to afford 2-substituted 3-t-butoxycarbonyl-4(3H)quinazolinones. The t-butoxycarbonyl group of these products was easily deprotected to give key intermediates for the synthesis of quinazoline derivatives, 2-substituted 4(3H)-quinazolinones, in good yield.

  Syntheses of both enantiomers of chrysogine, 2-(α-hydroxyethyl)-4(3H)-quinazolinone, 1 from 2-ammobenzamide are reported. Thus reaction of 2-aminobenzamide and optically active α-acetoxypropionyl chloride gave 9, which upon saponification and cyclization induced by aqueous sodium carbonate at room temperature gave chrysogine. The enantiomeric purity of 1 was determined by NMR. Inversion of (-)-(S)-1

  据报道，由2-氨苯甲酰胺合成了金葡胺的两种对映体2-（α-羟乙基）-4（3H）-喹唑啉酮1。因此，2-氨基苯甲酰胺与旋光性α-乙酰氧基丙酰氯的反应得到9，其在室温下由碳酸钠水溶液诱导的皂化和环化后得到金柳胺。通过NMR确定1的对映体纯度。使用Mitsunobo反应将（-）-（S）-1转化，得到（+）-（R）-1。的还原2 -乙酰基-4（3H）-qumazolinone 2与面包酵母，得到的S-对映体1。可以扩展使用的环化方法，并且还报道了许多2-（α-羟基）烷基-4-（3H）-喹唑啉酮。
