Divergent Copper‐salt‐controlled Reactions of Donor‐Acceptor Cyclopropanes and N ‐Fluorobenzene Sulfonimide: Access to the 1,3‐Haloamines and Aminoindanes

Autor: Lingyan Liu, Xiao Wang, Weiguo Xiao, Weixing Chang, Jing Li

Publikováno v: Chemistry – A European Journal. 29

We herein report a method for divergent copper salt controlled reactions of donor-acceptor cyclopropanes and N-fluorobenzene sulfonimide (NFSI). Specifically, in the presence of CuX

Au(I)/(R)-BINOL–Ti(IV) Concerted Catalyzed Asymmetric Cascade Cycloaddition Reaction of Arylalkynols

Autor: Tianlong Zeng, Lingyan Liu, Weixing Chang, Jing Li, Hongkai Wang

Publikováno v: Organic Letters. 23:3573-3577

An efficient catalytic asymmetric cascade cycloaddition reaction of arylalkynols with dioxopyrrolidines was developed. This reaction was achieved using Au(I) and (R)-BINOL-Ti(IV) bimetallic catalysts and exclusively delivered a series of chiral oxo-b

Stereospecific Synthesis of cis-2,5-Disubstituted Pyrrolidines via N,O-Acetals Formed by Hydroamination Cyclization–Hydroalkoxylation of Homopropargylic Sulfonamides in HFIP

Autor: Weixing Chang, Weiguo Xiao, Xiaodan Zuo, Xiaoyu Shi, Lingyan Liu, Weilin Wang, Xiaohui Cao, Jing Li

Publikováno v: The Journal of Organic Chemistry. 85:7045-7059

We reported a novel two-step stereoselective synthesis of functionalized pyrrolidines from homopropargylic sulfonamides and nucleophiles via an isolable N,O-acetals intermediates. This reaction fea...

Cocatalyst-controlled divergent cascade cycloaddition reaction of arylalkynols and dioxopyrrolidienes: access to spiroketals and oxa-bridged eight-membered cyclic ethers

Autor: Lingyan Liu, Tianlong Zeng, Weiguo Xiao, Weixing Chang, Songmeng Wang, Jing Li, Hongkai Wang, Xinhong Li

Publikováno v: Organic Chemistry Frontiers. 7:1809-1816

A cocatalyst-controlled divergent cascade cycloaddition reaction was developed for the synthesis of two different complex oxygen-containing heterocyclic compounds from arylalkynols and dioxopyrrolidienes in the presence of Au(I) catalyst. Using two d
