Bimolecular cobalt-catalyzed [2+2+2] cycloadditions between yne-ynamides and nitriles afford bicyclic 3- or 4-aminopyridines in up to 100% yield. The high regioselectivity observed depends on the substitution pattern at the starting ynamide. Aminopyridines bearing TMS and Ts groups are efficiently deprotected in an orthogonal fashion.
Silver-catalyzed cycloisomerization of 1,n-allenynamides
Garcia, Pierre,Harrak, Youssef,Diab, Lisa,Cordier, Pierre,Ollivier, Cyril,Gandon, Vincent,Malacria, Max,Fensterbank, Louis,Aubert, Corinne

A variety of allenynamides can undergo cycloisomerization reactions in the presence of silver triflate thus leading to the formation of N-containing heterocycles incorporating cross-conjugated trienes. Access to new dienic 4-piperidinone and azepane motifs was achieved. An extension to one-pot tandem sequences involving silver-catalyzed cycloisomerization/Diels-Alder reaction was also examined.
Rhodium(I)-catalyzed [2+2+2] cycloadditions with N-functionalized 1- alkynylamides: A conceptually new strategy for the regiospecific synthesis of substituted indolines
Witulski, Bernhard,Stengel, Thomas
, p. 2426 - 2430 (2007/10/03)
The regiospecific introduction of substituents into the 4-position of 2,3-dihydroindoles (indolines), which is significant for the synthesis of various natural products and pharmaceuticals, was achieved by rhodium(I)- catalyzed cyclotrimerizations of 1 wi
