Base-catalyzed tandem Michael/dehydro-Diels-Alder reaction of α,α-dicyanoolefins with electron-deficient 1,3-conjugated enynes: a facile entry to angularly fused polycycles.

Mingrui Zhang, +1 more
- 07 Jan 2014 - 
TL;DR: A base-promoted tandem Michael addition and DDA reaction of α,α-dicyanoolefins with electron-deficient 1,3-conjugated enynes was realized and control experiments support the stepwise anionic reaction pathway rather than the concerted reaction pathway.

Proline-based reduced dipeptides as recyclable and highly enantioselective organocatalysts for asymmetric Michael addition.

Xiaohui Cao, +6 more
- 09 Sep 2011 - 
TL;DR: A series of novel proline-based reduced dipeptides was developed and evaluated for a direct Michael addition of ketones and aldehydes to nitroalkenes and achieved excellent yields, diastereoselectivities and enantioselectivity in the presence of 5 mol% catalyst.

Synthesis of 6-Fluoroalkyl 6H-Benzo[c]chromenes via Visible-Light-Promoted Radical Addition/Cyclization of Biaryl Vinyl Ethers

Qinfei Deng, +4 more
- 16 May 2018 - 
TL;DR: A novel visible-light-promoted cascade cyclization reaction for the synthesis of 6-fluoroalkyl 6 H-benzo[ c]chromenes has been successfully realized and provided the desired products in moderate to good yields.

Combining prolinamides with 2-pyrrolidinone: Novel organocatalysts for the asymmetric aldol reaction

Ismini Vlasserou, +4 more
- 10 May 2018 - 
TL;DR: In this article, the combination of prolinamides with derivatives bearing the 2-pyrrolidinone scaffold, deriving from pyroglutamic acid, led to the identification of novel organocatalysts for the intermolecular asymmetric aldol reaction.
