The new spirocyclic compounds, spiropyrrolidinyl-benzoisothiazoline derivatives were synthesized by the 1,3-dipolar cycloaddition of benzoisothiazole-2,2-dioxide-3-ylidenes and azomethine ylide. The stereochemistry of 1,3-dipolar cycloaddition as well as the stereochemistry of Knoevenagel condensation of benzoisothiazole-2,2-dioxide with aldehydes were studied.

-
Paragraph 0104; 0109, (2018/03/25)
Disclosed are a condensed-ring pyrimidylamino derivative, a preparation method therefor, and an intermediate, a pharmaceutical composition and applications thereof. The method for preparing the condensed-ring pyrimidylamino derivative comprises: in a solvent, in the presence of a palladium-containing catalyst, allowing a compound represented by formula I-a and a compound represented by formula I-b' to have a coupling reaction, and then preparing a compound represented by formula I by means of a deprotection reaction. Also disclosed applications of the condensed-ring pyrimidylamino derivative in the preparation of drugs for preventing, relieving and/or treating tumors or diseases caused by an anaplastic lymphoma kinase. The condensed-ring pyrimidylamino derivative of the present invention has an obvious restraint effect on the anaplastic lymphoma kinase.

Synthesis of Phenanthridines through Palladium-Catalyzed Cascade Reaction of 2-Halo-N-Ms-arylamines with Benzyl Halides/Sulfonates
Yang, Si-Yi,Han, Wen-Yong,Zhang, Ding-Lei,Zhou, Xiao-Jian,Bai, Mei,Cui, Bao-Dong,Wan, Nan-Wei,Yuan, Wei-Cheng,Chen, Yong-Zheng
, p. 996 - 1003 (2017/02/15)
An efficient palladium-catalyzed nucleophilic substitution/C–H activation/aromatization cascade reaction between readily available 2-halo-N-Ms-arylamines (Ms = methanesulfonyl) and benzyl halides/sulfonates has been described. A wide variety of phenanthridines were synthesized in a one-pot fashion in moderate to high yields (37–86 %). Notably, this method provides a straightforward, facile approach for the synthesis of phenanthridines. The practicality was further substantiated by successfully carrying out a gram-scale preparation.
