, p. 423 - 424 (1995)
Three components coupling reactions between aldehydes, amines, and dienes or alkenes were catalyzed by lanthanide or scandium triflate to afford pyridine and quinoline derivatives in high yields.The Lewis acid catalysts were stable and kept their activity
Bismuth(III) chloride and triflate: New efficient catalysts for the Aza-Diels-Alder reaction
Laurent-Robert,Garrigues,Dubac
, p. 1160 - 1162 (2007/10/03)
Bismuth(III) chloride (1) and triflate (2) are excellent catalysts of hetero Diels-Alder reactions of imines 3-6 with diene 7 or dienophiles 8 and 9. A one-pot procedure with in situ production of imine from the corresponding aldehyde and amine was possib
