On August 25, 2020, Zhang, Xingxian; He, Kailun; Wang, Wenbing published a patent.Category: esters-buliding-blocks The title of the patent was Preparation of lenalidomide derivatives as antitumor agents. And the patent contained the following:
The invention discloses a preparation of lenalidomide derivative with general formula I as antitumor agents [wherein A = (CH2CH2X)n, n = 1 to 6; X = O or CH2]. For example, compound I (n = 2, X = O) was prepared in a multi-step synthesis. The title compounds have good antitumor activity and EGFR protein degradation level, which can be used to prepare antitumor agents. The experimental process involved the reaction of tert-Butyl 2-(2-(2-(tosyloxy)ethoxy)ethoxy)acetate(cas: 882518-89-0).Category: esters-buliding-blocks
