Good nucleophilicity of the ring nitrogen in chiral (2R,10R)-2-acyl-(10-phenylethyl)aziridines initiated the reaction with various acid chlorides to form the corresponding acylaziridinium ion… (More)
The deacetylenative coupling reaction of two terminal propargylic amines is accomplished in the presence of a copper(I) catalyst and the absence of a base to give the diaminobutynes (II).
Enantiomerically pure 3-substituted-5-amino-4-hy- droxy-5,6-dihydro-4H-pyrrolo(1,2-c)(1,2,3)triazoles were synthe- sized efficiently from the sequential reactions including a regioselective… (More)
Optimized conditions allow the preparation of a broad spectrum of substituted propargylic amines bearing various functionalities.
The catalytic deacetylenative coupling reaction of terminal alkynes with various N-substituted propargylic amines proceeded in the presence of CuCl (10 mol%) and Na 2 HPO 4 (4 equiv) in THF at 130 °C… (More)
