Method for producing aluminum salts of cyclic phosphinic acids

A process for the preparation of aluminum salts of cyclic phosphinic acids is described, which comprises reacting cyclic phosphinic acids, such as 1-hydroxydihydrophosphole oxides or 1-hydroxyphospholane oxides, with aluminum hydroxide in the presence of water and in the absence of polar solvents at elevated temperature for a reaction time of from 1 to 20 hours.

Method for producing aluminium salts of cyclic phosphinic acid

The invention relates to a method for producing aluminum salts of cyclic phopshinic acid. According to the invention, cyclic phosphinic acids, such as 1-hydroxydihydrophosphole oxide or 1-hydroxyphospholane oxide, are reacted with a basic aluminum acetate, such as hydroxyaluminum diacetate, in the presence of water and in the absence of polar solvents with heat for a reaction time of 1 to 20 hours.

A NEW REAGENT FOR THE MEDIATION OF AMIDE BOND FORMATION IN PEPTIDE SYNTHESIS.

The potential application of 1-oxo-1-chlorophospholane (5) as a novel reagent for the in situ activation of N α-protected amino acids for use in peptide bond forming reactions has been examined.Wherever possible, 32.4 MHz 31P nuclear magnetic resonance (n.m.r.) spectroscopy was employed to follow both the formation of the intermediate phospholanic-carboxylic mixed anhydride and the subsequent aminolysis reaction.
