The regio- and stereoselectivity of the addition reactions of O-, C-, N-, and S-nucleophiles to l-arabinal-derived vinyl epoxide 2, the simplest non-conformationally restricted glycal-derived vinyl epoxide, has been examined and compared with the corresponding, conformationally restricted d-galactal-derived analogs 1β and 1β-Me. Results indicated that the 1,4-/1,2-regioselectivity ratio and the related
