Organocatalytic Enantioselective Protonation for Photoreduction of Activated Ketones and Ketimines Induced by Visible Light.

Angewandte Chemie (International ed. in English)

Lin L, Bai X, Ye X, Zhao X, Tan CH, Jiang Z.
PMID: 28925022
Angew Chem Int Ed Engl. 2017 Oct 23;56(44):13842-13846. doi: 10.1002/anie.201707899. Epub 2017 Oct 04.

The first catalytic asymmetric photoreduction of 1,2-diketones and α-keto ketimines under visible light irradiation is reported. A transition-metal-free synergistic catalysis platform harnessing dicyanopyrazine-derived chromophore (DPZ) as the photoredox catalyst and a non-covalent chiral organocatalyst is effective for these transformations....

Acute Post Surgical Pain may result in chronic post surgical pain: A Systemic Review and Meta Analysis.

Org Biomol Chem. 2015 Nov 28;13(44):10929-38. doi: 10.1039/c5ob01374g. Epub 2015 Sep 16.

The domino cycloaddition reactions of N-phenacylbenzothiazolium bromides with 3-phenacylideneoxindoles or ethyl 2-(2-oxoindolin-3-ylidene)acetates in ethanol at room temperature in the presence of triethylamine as a base afforded functionalized spiro[benzo[d]pyrrolo[2,1-b]thiazole-3,3'-indolines] in good yields and with high diastereoselectivity. The similar reactions of...

Squaramide-catalysed asymmetric cascade aza-Michael/Michael addition reaction for the synthesis of chiral trisubstituted pyrrolidines.

Organic & biomolecular chemistry

Zhao BL, Lin Y, Yan HH, Du DM.
PMID: 26426388
Org Biomol Chem. 2015 Dec 14;13(46):11351-61. doi: 10.1039/c5ob01749a.

A bifunctional squaramide catalysed aza-Michael/Michael cascade reaction between nitroalkenes and tosylaminomethyl enones or enoates has been developed. This organocatalytic cascade reaction provides easy access to highly functionalized chiral pyrrolidines with a broad substrate scope, giving the desired products in...
