V. Dalla et P. Pale, CHEMISTRY OF 3,4-EPOXY-2-METHYLENE OXOLANES - HIGHLY DIASTEREOSELECTIVE ELECTROPHILIC ADDITIONS, Tetrahedron letters, 37(16), 1996, pp. 2777-2780
electrophilic additions to the enol ether part of 3,4-epoxy-2-methylen
e oxolanes are described. The isomer resulting from an anti addition r
elative to the oxirane substituent was predominantly obtained. With ph
enylselenyl bromine as electrophile, a complete diastereoselectivity w
as achieved again in favor of the trans isomer. Copyright (C) 1996 Pub
