T-type calcium channel antagonist activity, and new 4-methylene-quinazolin-2-ones, promising catalysts as N-heterocyclic olefins, have been prepared in good yield by a simple reaction between 2-aminobenzophenone, or 2-aminoacetophenone, and cyanomethyl anion electrogenerated by acetonitrile reduction at a graphite electrode, followed by the addition of different organic isocyanates and subsequent heterocyclization
良好制备了一系列具有潜在T型钙通道拮抗剂活性的3,4-二取代喹唑啉-2-酮和新的4-亚甲基喹唑啉-2-酮,它们有望成为N-杂环烯烃的催化剂。通过2-氨基二苯甲酮或2-氨基苯乙酮与通过在石墨电极上乙腈还原电生成的氰基甲基阴离子之间的简单反应,然后添加不同的有机异氰酸酯和随后的杂环化反应,可得到高收率。
