    • Presumably, the reaction proceeds via the Diels-Alder-like endo transition structure I, featuring a Felkin-type facial diastereoselectivity (addition of the aldehyde from the re-face). The transition state I then collapses to afford the major 4S,5R-configured adduct 10. Formation of the minor 4R,5R isomer 11, in contrast, would require a high-energy exo transition state II possessing an unfavorable orientation of the aldehyde dioxolanyl substituent. (diagram presented). For a recent theoretical study of the mechanisms of related Lewis acid assisted reactions involving five-membered heterocyclic dienes, see: Yu, Z.-X.; Wu, Y.-D. J. Org.
