Electrophilic selenocyclization in 2-ene-1,5-diol systems : unexpected oxetane vs. tetrahydrofuran formation

Tetrahedron 59 (37) 7365-7376

par Frapart - publié le

Abstract :

Electrophile-induced cyclization of (E)- and (Z)-2-ene-1,5-diols to tetrahydrofurans and oxetanes is described. Significant differences between the present report and previous work have been noted. A tentative model is proposed.
