Electrophilic selenocyclization in 2-ene-1,5-diol systems: unexpected oxetane vs. tetrahydrofuran formation
摘要:
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. (C) 2003 Elsevier Ltd. All rights reserved.
