G. Keglevich et al., Convenient method for the reduction of the double-bond of cyclic vinylphosphine oxides using borane, SYN COMMUN, 30(23), 2000, pp. 4221-4231
The electronpoor double-bond of cyclic vinylphosphine oxides (1, 3 and 4) i
s easily reduced by borane in a selective manner to give the corresponding
saturated derivatives (2, 4 and 5, respectively) Under forcing conditions,
change of the functionality may also take place.
