    • When adduct 3ac was heat at 80 °C in DCE for 1 h, a significant decrease of diastereomeric ratio was observed (from 10: 1 to 5: 1) As a reference experiment, the cycloaddition of alkynes 2a and 2c with a diyne, in place of enynes, was examined under the same reaction conditions: the reaction of alkyne 2c achieved much higher enantioselectivity than that of 2a (details in supplemental information). These results suggest that diastereoselectivity was determined by the induction of axial chirality at the stage of alkyne insertion
