The present invention relates to novel spiro-oxazine analogues of Formula-I and Indolinone compounds of Formula-II or positional isomers, or stereoisomers, or derivatives, or pharmaceutically acceptable salt thereof. Formula-I Formula-II Further the invention provides transition- metal free multicomponent reaction (MCR) process for the preparation of said compounds of Formula-I and II using aryne precursor, N-substituted isatin and N-heteroaromatic compound as the nucleophile,under mild condition leading to formation of desired complex of spiro-oxazine analogues (I) and indolinone analogues (II) in high yield and selectivity.
本发明涉及式I的新型螺环氧化吲哚类似物和式II的吲哚酮化合物或其位置异构体、对映异构体、衍生物或药用可接受盐。进一步地,本发明提供了一种无需过渡金属的多组分反应(MCR)过程,用于在温和条件下使用芳炔前体、N-取代异色满和N-杂芳族化合物作为亲核试剂来制备式I和II的化合物,从而高收率和选择性地形成所需的螺环氧化吲哚类似物(I)和吲哚酮类似物(II)的复杂结构。
