Intramolecular Nitrogen-Phosphorus Interactions of Phosphate Esters

Article abstract of DOI:10.1021/jo00212a017

Four different classes of phosphate esters derived from enols, phenols, carbinols, and oximes have been shown to undergo intramolecular rearrangements assisted by a neighboring nitrogen.The unexpected products from these rearrangements have been characterized by spectral methods, especially 13C NMR.Rearrangements involving the O-ethyl S-propyl thiophosphate group have led to particularly interesting results.
