Ma, Zhiwei; Liu, Xiaofeng; Liu, Juntao; Tao, Jingchao published the artcile< Highly enantioselective Michael addition catalyzed by new primary amine-squaramide organocatalysts>, Electric Literature of 112-63-0, the main research area is enantioselective Michael addition primary amine squaramide organocatalyst.
The asym. Michael addition reaction of α,α-disubstituted aldehydes to maleimides catalyzed by new bifunctional primary amine-squaramides has been developed. This organocatalytic asym. reaction provides easy access to functionalized succinimides with a broad substrate scope. Both enantiomers of desired succinimide derivatives were obtained in good to excellent yields (up to 98%) with excellent enantioselectivities (up to > 99% ee).
Youji Huaxue published new progress about Michael reaction. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Electric Literature of 112-63-0.
