allyl amines and 3-vinylaziridine-2-oxindoles have been accomplished in good yield via InCl 3 /ArSH-mediated ring opening of 3-vinylaziridine-2-oxindoles and sulfur ylide aziridination, respectively. The sulfur ylide was generated in situ from the bromo isomerized Morita–Baylis–Hillman adduct of isatin with N -tosyl imines and tetrahydrothiophene under basic conditions.
分别通过 InCl 3 /ArSH 介导的 3-乙烯基氮丙啶-2-羟吲哚开环和硫叶立德氮丙啶化反应,以良好的收率快速高效地合成了 oxindole 附加的烯丙基胺和 3-vinylaziridine-2-oxindole。硫叶立德是在碱性条件下由靛红与 N-甲苯磺酰亚胺和四氢噻吩的溴异构 Morita-Baylis-Hillman 加合物原位生成的。
