The reaction product described in entry 7 of Table 2 was incorrectly assigned as the 2-carbomethoxy-3-vinyl-γlactone 5c (1:1 diastereomeric mixture). Further analyses revealed it to be the isomeric 2-carbomethoxy-4-vinyl-γ-lactone. See also: Silvestri, M. A.; He, C.; Khoram, A.; Lepore, S. D. Tetrahedron Lett. 2006, 47, 1625.
