The synthesis of aryl-substituted 1,4-dihydroquinolines can be achieved using a [4+2] cycloaddition between benzyne and various aryl-substituted 1-azadienes. The conditions are tolerated by N-aryl-, alkyl-, tosyl-, and tert-butoxycarbonyl-protected 1-azadienes. A short synthesis of the fungal metabolite 3-O-methylviridicatin is reported. benzyne - dihydroquinolines - azadienes - cycloaddition - 3
芳基取代的1,4-二氢喹啉的合成可以使用苯并炔和各种芳基取代的1-氮二烯之间的[4 + 2]环加成反应来实现。N-芳基- ,烷基-,甲苯磺酰基-和叔丁氧羰基保护的1-氮杂二烯可耐受这些条件。据报道,真菌代谢物3- O-甲基病毒素的合成很短。 苯并-二氢喹啉-氮杂二氮-环加成-3- O-甲基viridicatin
