A novel Diels–Alder (DA) reaction with 4-nitro-1(2H)-isoquinolones acting as the dienophile afforded 5(6H)-phenanthridone derivatives. The DA reaction of 4-nitro-1(2H)-isoquinolone with 1-methoxy-1,3-butadiene gave biologically active 5(6H)-phenanthridone possessing in a high yield. Regioselectivity of 4-nitro-1(2H)-isoquinolones with 1-methoxy-3-silyloxy-1,3-butadiene was calculated using molecular orbital (MO) calculations.
以 4-硝基-1(2H)-异喹啉酮为亲二烯的新型 Diels-Alder (DA) 反应生成了 5(6H)-phenanthridone 衍生物。4- 硝基-1(2H)-异喹啉酮与 1-甲氧基-1,3-丁二烯的 DA 反应能以高产率得到具有生物活性的 5(6H)-菲啶酮。利用分子轨道(MO)计算法计算了 4-硝基-1(2H)-异喹啉酮与 1-甲氧基-3-硅氧基-1,3-丁二烯的区域选择性。
