In general, the cycloaddition reactions of 1,6-enynes via rhodacyclopentene A are highly enantioselective. For representative examples of the asymmetric [2+2+1] cycloadditions (Pauson-Khand reactions), see: a) N. Jeong, B. K. Sung, Y. K. Choi, J. Am. Chem. Soc. 2000, 122, 6771

for examples of the asymmetric [2+2+2] cycloadditions, see: references [3] and [9b-d]. Similarly, the reaction of 1j and 2a furnished the corresponding cyclohexene 3ja with a high ee value and the corresponding diene 4ja with a low ee value, although 4ja could not been isolated in a pure form by silica gel chromatography
