A closely related terminal alkynyl-ene substrate was reported in reference [3d] to undergo a rapid cyclization (< 5 min, 100% conversion) in the presence of a catalytic system generated in situ by sequential mixing of, Rh(cod)Cl}2, S)-binap, substrate (1 min, and AgSbF 6 in DCE at room temperature to afford a related product in poor enantioselectivity (i.e. 6.5% ee, see experimental and footnote 14c in reference [3d, The key to the success of our protocol is the use of preformed, more well-defined catalyst [Rh, S)-binap)]SbF6. The precise mechanistic differences between the two catalytic systems, however, remain to be elucidated, although the undefined nature of the catalytic species in reference [3d] and the slower reaction rates (12-16 h reaction times at room temperature) under our reaction conditions may be important factors
