PPh3-Catalyzed aza-MBH domino reaction of salicyl N-tosylimines with γ-CH3 substituted allenoates is reported. Readily available imines and allenoates are converted to benzoxazepine derivatives in one step. Wherein, functionalization of C–H bonds of γ-substituted allenoate has been developed in this domino process.
报告了 PPh3 催化的水杨基 N-对甲苯磺酸亚胺与 γ-CH3 取代的异烯酸酯的偶氮-MBH 多米诺反应。现成的亚胺和异烯酸酯可一步转化为苯并氧氮杂卓衍生物。在这一多米诺过程中,γ-取代的异烯酸酯的 C-H 键功能化得到了发展。
