Augmentation of Enantioselectivity by Spatial Tuning of Aminocatalyst: Synthesis of 2-Alkyl/aryl-3-nitro-2 H-chromenes by Tandem Oxa-Michael-Henry Reaction
Bez, Ghanashyam,Mohanta, Rahul
, p. 4627 - 4636 (2020/05/01)
The asymmetric oxa-Michael addition of salicylaldehyde to conjugated nitroalkenes often suffers from poor reactivity and selectivity and a long reaction time. Because of the formation of an iminium ion with aminocatalyst, the nucleophilicity of the phenol

An expedient one-pot sequential three-component synthesis of a series of diverse spiroindenoquinoxaline pyrrolidine fused nitrochromene derivatives following 1,3-dipolar cycloaddition of azomethine ylides generated in situ by the condensation of indenoqui
Assembly of fully substituted triazolochromenes via a novel multicomponent reaction or mechanochemical synthesis
Vroemans, Robby,Verhaegen, Yenthel,Dieu, My Tran Thi,Dehaen, Wim
supporting information, p. 2689 - 2697 (2018/11/03)
A new metal-free one-pot three-component procedure towards fully substituted triazolochromenes has been developed, starting from commercially available materials. Salicylaldehydes and nitroalkenes were reacted under solvent-free conditions, followed by a
