straightforward protocol for 1,2,4-triazoline-fused dibenzo[b,f][1,4]oxazepines is effectively established through KI/TBHP-promoted [3+2] annulation between dibenzo[b,f][1,4]oxazepine-imines and N-tosylhydrazones under mild conditions. The produced 1,2,4-triazoline-fused DBOs could be easily converted into biologically interesting 1,2,4-triazolo-fused DBOs with excellent yields
通过 KI/ TBHP促进的二苯并 [ b ,f ][1, 4]oxazepine-imines 和N - tosylhydrazones 在温和条件下。所生产的 1,2,4-三唑啉融合 DBO 可以很容易地转化为具有生物学意义的 1,2,4-三唑并融合 DBO,并且产率很高
