“…Ynamides are also interesting reaction partners for cyclotrimerization or—more generally—[2+2+2] cycloadditions because the polarization of the triple bond can greatly affect the regiochemical outcome of such transformations. Indolines or carbazoles 122 are formed with high efficiency when starting from yne‐ynamides 121 (Scheme ) 17c,f. The regioselectivity of the reaction, which was shown to depend on steric interactions with the substituents of the yne‐ynamide, could be elegantly reversed by switching from the Wilkinson to the Grubbs catalyst, thereby producing 4,5‐ or 4,6‐disubstituted indolines selectively from terminal ynamides ( 121 , R′′=H) and alkynes ( 120 , R or R′=H) 17e…”
