Betaine aspartate was prepared from betaine and L-aspartic acid (molar ratio 1 1) in aqueous solution at pH 5.7-5.0. 

Phosphonic acid analogues of aspartic acid, glutamicacid C-benzy1g1ycine,191 and the phosphor inane (70)1 92 have been studied, also the oxime (71)193 a phosphonopiperidinol - with a very distorted chair structure,194 the phosphonate (72),195 a pyrazole,196 a thiocarbamoy1phosphonate, 97 and two iminobis-(methylphosphonic acids).198 Additionally there have been studies of the new bicyclic sulphur heterocycle (73),199 the oxazaphospho1idine (74)200 and a triaminophosphetanium aluminium betaine.201... 

A number of betaines of type (7) have been prepared as potential antibiotic analogues of fi-lactams and were found to inhibit serine and aspartic proteases <92EJM193,93JPP(45)466>.

The synthesis of monoesters based on perfluorinated alcohols and aspartic or glutamic acid has been reported, and the corresponding betaines (24) have been prepared (Scheme 21). The yields for these reactions are universally poor, however [15]. 

Alkylbetaine esters [90-92], quaternized aspartic acid esters [23], and polyolesters of betaine [71] have been suggested for use in fabric care. The ester bond in betaine esters is strongly activated by cationic nitrogen in the a position, and therefore these materials can undergo rapid abiotic degradation and have very low aquatic toxicity.
