    • The presence/absence of bipy had little affect on the yield of 2; however, 6 mol % of bipy significantly affected the yield of cyclopropane for some other enynes (see Table SI). The specific role of bipy in these transformations is currently under investigation.

    • Compound 8 was isolated from reactions of (Z)-5 as predominantly one diastereomer. (Notably, isolation of the corresponding product from (E)-5 was challenging due to the low yield of this reaction.) The stereochemistry of 8 could not be definitively established using coupling constant analysis. Efforts to obtain a crystalline derivative of 8 are ongoing and will be reported in a full paper.
