supporting information; experimental part, p. 6980 - 6982 (2010/11/24)

In the absence of any catalysts, ortho-alkynylanilines react with aldehydes and amines in HFIP to form trans-2,3-disubstituted 2,3-dihydro-4- iminoquinolines in a complete trans-selective manner via the three-component alkyne-imine metathesis.
