Resumo(s)
In the presence of a base, chlorohydroxyiminophosphonates are converted in situ
into the corresponding transient nitrosovinylphosphonates, which react as heterodienes
with electron-rich alkenes and heterocycles producing oxazines and open-chain
oximes in moderate yields and good selectivity. This approach may be regarded as
a new strategy for the synthesis of precursors of α-amino phosphonic acids.
