A KINETIC STUDY OF PHOSPHINIC CARBOXYLIC MIXED ANHYDRIDES

Ramage, Robert,Atrash, Butrus,Hopton, David,Parrott, Maxwell J.

, p. 1617 - 1622 (2007/10/02)

Using 32.4 MHz (31)P n.m.r. spectroscopy, disproportionation of a series of phosphinic carboxylic mixed anhydrides derived from protected α-amino acids has been studied both as a function of the substituents at phosphorus and structure of the α-amino acid being activated.It was found that the rates of disproportionation were insignificant from a preparative aspect compared with aminolysis at 0 deg C.
