    • To the best of our knowledge, there is only one article in which the abnormal product 2 was recorded as a minor by-product by Roush and co-worker, cf.: W.R. Roush, and S. Rodriguez-Russo J. Org. Chem. 52 1987 603 606 Although Corey and Chaykovsky had described the production of a hydroxy-bearing (according to IR analysis) side-product in their original report (see Section 2 of Ref. 1d), they did not characterize its structure then

    • In contrast with this remarkable regioslectivity, diol 9 was prepared from triene 7 by Sharpless dihydroxylation with an AD-mix reagent system in a rather low yield (ca. 10%, poor regioselectivity). Similarly, electrophilic epoxidation of triene 7 with m-CPBA also lacks regioselectivity for the production of labile epoxide 5.

    • This is apparently due to the inherent preference for the oxy-3-exo-tet ring closure process. It is evident that the addition of metal (Li, Na, or K) iodide in the reaction mixture (i.e., reaction in Table 1) could not increase the yield of the sulfide formation.
