This approach may be regarded as a new strategy for the synthesis of precursors of α-amino phosphonic acids.engNitrosoalkeneDiels-AlderA-aminophosphonatesNitrosovinylphosphonatesHeterocyclesCicloadiçãoReactions of nitrosovinylphosphonates with electron-rich alkenes and heterocyclesjournal article2012-04-13
