  Esters of (het)aroylpyruvic acids can react with o-phenylenediamine, leading to the formation of (Z)-3-(2-(het)aryl-2-oxoethylidene)-3,4-dihydroquinoxalin-2(1H)-ones and 4-(het)aryl-3H-1,5-benzodiazepine-2-carboxylates. The obtained product ratio depends on the electronic effects due to substituents in the (het)aroyl moiety of (het)aroylpyruvate esters and the reaction conditions. The highest ratio

  (杂)芳酰基丙酮酸的酯可以与邻苯二胺反应，导致形成 ( Z )-3-(2-(杂)芳基-2-氧代亚乙基)-3,4-二氢喹喔啉-2(1 H )-和4-(杂)芳基-3H- 1,5-苯二氮卓-2-羧酸酯。所获得的产物比率取决于由于(杂)芳酰基丙酮酸酯的(杂)芳酰基部分中的取代基所产生的电子效应和反应条件。当使用不带取代基的(杂)芳酰基丙酮酸酯时，以及在乙酸中进行反应时，观察到与药物化学相关的喹喔啉酮的最高比例，取代基会导致(杂)芳酰基部分产生负面介观效应。

  A microwave-assisted, environmentally benign green protocol for the synthesis of functionalized (Z)-3-(2-oxo-2- phenylethylidene)-3, 4-dihydro-2H-benzo[b][1,4] oxazin-2-ones (11a-n) in excellent yields (upto 97%) and (Z)-3-(2-oxo-2-phenylethylidene)-3,4-dihydroquinoxalin-2(1H)-ones (14a-h) (upto 96% yield) are reported. The practical applicability of developed methodology were also confirmed by the gram scale synthesis of 11a, 14c and 14e; synthesis of anticancer alkaloid Cephalandole A 16 (89% yield). All the synthesized compounds 11a-n, 14a-h and 16 were assessed for their in vitro antioxidant activities in DPPH radical scavenging and FRAP assay. In DPPH assay, compounds 11a, 14c and 14e, the most active compounds of the series, were found to show IC50 value of 10.20 +/- 0.08 mu g/mL, 9.89 +/- 0.15 mu g/mL and 8.97 +/- 0.13 mu g/mL, respectively in comparison with standard reference (ascorbic acid, IC50 = 4.57 mu g/mL). Whereas, in FRAP antioxidant assay seven compounds (11c, 11e, 11i, 11k, 11l, 14d and 14h) displayed higher antioxidant activity in comparison to the reference standard BHT (C-0.5 FRAP = 546.2 mu M). Moreover, the cytotoxic studies of the compounds 11a, 14c, 14e and 14h were found to be non-toxic in nature in 3T(3) fibroblast cell lines using MTT assay.
