(2Z)-alkenylamine and (3Z)-alkenylol derivatives in high yields in a regio- and stereoselective manner through the deuterolysis (or hydrolysis). The reaction of substituted propargylamines and homopropargylic alcohols with the in situ generated low-valent niobium complex (based on the reaction of NbCl5 with magnesium metal) is an efficient tool for the synthesis of allylamines and homoallylic alcohols bearing a 1,2-disubstituted

A range of alkynyldimethylaluminum reagents were added to N,N‐disubstituted formamides and the their acetals to provide the corresponding N,N‐disubstituted 3‐amino‐1,4‐diynes. Also, these reagents smoothly underwent the addition to N,O‐acetals to give the corresponding N,N‐disubstituted 3‐amino‐1‐ynes.

A general and effective procedure has been developed for the synthesis of symmetrical and unsym- metrical 2,3-acetylenic amines by aminomethylation of terminal mono- and diacetylenes with geminal diamines in the presence of transition metal salts and complexes.
