Li, Sifeng; Yang, Qingjing; Wang, Jun published the artcile< Copper(II) triflate-catalyzed highly efficient synthesis of N-substituted 1,4-dihydropyridine derivatives via three-component cyclizations of alkynes, amines, and α,β-unsaturated aldehydes>, Reference of 3893-18-3, the main research area is pyridine dihydro preparation; three component reaction alkyne amine unsaturated aldehyde copper catalyst; dihydropyridine preparation.
A copper(II) triflate-catalyzed three-component cyclization of alkynes, amines, and α,β-unsaturated aldehydes was developed to give various 1,4-dihydropyridines in good to high yields. In addition, this efficient and practical protocol proceeded smoothly in gram scale even when the catalytic loading was reduced to 1 mol %.
Tetrahedron Letters published new progress about Alkynes Role: RCT (Reactant), RACT (Reactant or Reagent). 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, Reference of 3893-18-3.
