Panse, G. T.,Kamat, S. K.
, p. 793 - 795 (2007/10/02)
N,N'-bis-morpholinophosphinic chloride (BMP-Cl) has been successfully used as a coupling reagent for first time in the peptide synthesis.Few peptides have been prepared using this coupling reagent and the results have been compared with those obtained by anhydride method.
AMIDATION OF HALOGEN DERIVATIVES OF PHOSPHORUS WITH 4,4',4''-METHYLIDYNETRISMORPHOLINE
Shevchenko, M. V.,Kukhar', V. P.
, p. 1336 - 1340 (2007/10/02)
4,4'4''-Methylidynetrismorpholine amidates polyhalophosphorus compounds and is a more reactive agent than the previously studied N,N,N'N'-tetraalkylmethanediamines.The dimorpholinomethylium chloride formed as a result of the reaction does not react with the amidation products, which makes it possible to isolate them in a pure state.
Some Derivatives of Morpholinophosphorodichloridate and dichloridothioate
Cremlyn, Richard J.,Patel, Kantilal,Wu, Luke
, p. 1457 - 1464 (2007/10/02)
Morpholinophosphorodichloridate and dichloridothioate reacted with amines (2 molar equivalents) to give the amidic chlorides which were treated with nucleophilic reagents to give sixty-four derivatives.However the dichloridothioate with primary amines (1
