[3+2] Cycloaddition of 1,3,5‐Triazinanes with Donor‐Acceptor Aziridines and Their Anti‐Tumor Activity
cycloaddition of 1,3,5-triazinanes with donor-acceptor aziridines has been developed, accessing diverselysubstituted imidazolidines high efficiency. Mechanistic investigations support the formation of imidazolidines through an SN1-like pathway. Furthermore, these imidazolidines exhibit promising anti-tumor activity against a series of human cancer cell lines.
已经开发了AY(OTf)3催化的供体-受体氮丙啶与1,3,5-三嗪并[3 + 2]环加成反应,可高效获得各种取代的咪唑烷。机理研究支持通过S N 1样途径形成咪唑烷。此外,这些咪唑烷类化合物显示出对一系列人类癌细胞系的有希望的抗肿瘤活性。

Aziridination of N-tosylimines with activatedmethylenecompoundsinduced by iodobenzenediacetate [PhI(OAc)2] and tetrabutylammonium bromide [Bu4NBr] afforded the corresponding 2,2-difunctionalized aziridines in good yields with the aid of a catalytic amount of base. The reaction is hypothesized to proceed via a tandem nucleophilic addition-oxidative cyclization pathway.

Lewis acid-catalyzed [3 + 3] cycloaddition reaction of donor‒acceptor aziridines with N,N-dialkyl-3-vinylanilines has been developed for the stereoselectivesynthesis of tetrahydroisoquinolines (THIQs). The reaction performed using Gd(OTf)3 as the Lewis acid catalyst was tolerant to various N-tosylaziridine and N,N-dialkyl-3-vinylaniline substrates and provided access to highly functionalized THIQs

A Lewisacid-catalyzed Friedel-Crafts/Michael cascade reaction between N-dialkyl-3-vinylanilines and N-tosylaziridines has been developed for the stereoselective synthesis of tetrahydroisoquinolines (THIQs). The reaction using Gd(OTf)3 as the Lewis acid catalyst was tolerant to the various N-dialkyl-3-vinylaniline and N-tosylaziridine substrates and provided access to 28 new, highly functionalized THIQs
