Horner-Wittig Reactions of β-Aminoalkyl- and β-N-Acylaminoalkyldiphenylphosphine Oxides: Synthesis of N-Allyl Amines and Amides and 5-Diphenylphosphinoyl-2-phenyl-5,6-dihydro-4H-1,3-oxazines

Lithium derivatives of β-diphenylphosphinoyl-alkyl amines and dilithium derivatives of the corresponding amides combine with aldehydes or ketones in the Horner-Wittig reaction.Separation of the diastereoisomeric intermediates leads to single positional and geometrical isomers of N-allyl amines and amides.Attempted rearrangement of the same intermediates in acid solution gives dihydro-oxazines or, in one cases, a γ-N-acylaminoallyl diphenylphosphine oxide.

E and Z allyl amides are formed with full regio- and stereochemical control from dianions of β-(acylamino)alkylphosphine oxides by the Horner-Wittig reaction.
