[2 + 2] cycloaddition of cyclic vinyl phosphonates with ketenes
Ruder, Suzanne M.,Ding, Min
, p. 1771 - 1776 (2007/10/03)
Highly substituted cyclic β-alkoxyvinyl phosphonates underwent thermal [2+2] cycloaddition with activated ketenes to afford bicyclic phosphonates. Fragmentation of the central polarized bond of this bicyclic system occurred readily upon treatment with zin
