Related Products of 894493-95-9. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 894493-95-9, Name is (1S,2S)-N1,N1-Dimethylcyclohexane-1,2-diamine. In a document type is Article, introducing its new discovery.
A series of multifunctional catalysts with two chiral diaminocyclohexane units were developed and successfully applied in the asymmetric oxa-Michael-aza-Henry cascade reaction of salicylaldimines with nitroolefins. This approach provides a simple and efficient entry to polysubstituted chiral 4-aminobenzopyrans with three consecutive stereocenters and in high yield (up to 97%) with excellent stereoselectivity (up to 98% ee and >99:1 dr). Facile access to the nonsymmetric optically pure 3,4-diaminochromanes was also obtained.
