“…2‐Trifluoromethyl‐1,3‐enynes are versatile synth‐ons in making various types of fluorinated functionlized carbocycles such as cyclopentane, benzene and naphthalene derivatives and fluorinated heterocycles such as pyrrole, cyclic nitrone, isoxazole, 4 H ‐pyran, 2‐pyrroline, pyrrolidine and tetrahydro‐pyridine via transition metal catalyzed or simple base mediated cascade reactions . The synthetic application of 2‐trifluoromethyl‐1,3‐enynes has been thoroughly investigated by several research groups including Trost, Gevorgyan, Zhang, Jeong, and our group…”
