Phosphates 3-hydroxyethyl esters

The equilibrium interconversion between an ethylene phosphite and a bicyclic spirophosphorane is shown to proceed by the insertion of the phosphite into the labile O-H bond of the hydroxyethyl ester. The mechanism is similar to the insertion of carbenes or nitrenes. Energy relationships of reaction intermediates were studied by MO RHF, MP2(full), MP4SDTQ, and DFT calculations. In most cases, they predicted that hydroxyethyl ethylene phosphates were more stable than the strained spirophosphoranes, which is not supported by the experimental evidence. The best correspondence to experimental data was obtained by DFT calculations with Perdew-Wang correlation functions <2003JST35>.

In the preparation of surfactants by the reaction of alcohols with P4Ol0 with subsequent neutralization of the partial phosphate esters with a base, the quality of the surfactants is improved by using RNEt3OH (R = Et or benzyl) in alcoholic solution as the base, by using C6 10 alcohol mixtures of hydroxyethylated C7 9 alcohols or equimolar mixtures of C6 I0 alcohols with polyethylene glycol (mol wt 200-1500) and by using a reaction temperature of 55-60°C [8]. 

It has been known that a micelle of l-hydroxyethyl-2-dimethylhexadecyl-ammonium bromide [21] exhibits high nucleophilic reactivity towards phosphate esters, carboxylic esters, 2,4-dinitrohalobenzene, etc. (Bunton et al., 1970 Bunton and Minch, 1970 Bunton and Ionescu, 1973 Martinek et al., 1975b Bunton and Diaz, 1976 Moss et al., 1975 Bunton and McAneny, 1977 Pillersdorf and Katzhendler, 1979). In the hydrolysis of PNPA, for example, the apparent rate constant for [21] is greater by a factor of 14 than that for choline (CH3 instead of C16Hjj in [21]) (Moss et al., 1975). However,... 

Thiamin is synthesized in bacteria, fungi, and plants from 1-deoxyxylulose 5-phosphate (Eq. 25-21), which is also an intermediate in the nonmevalonate pathway of polyprenyl synthesis. However, thiamin diphosphate is a coenzyme for synthesis of this intermediate (p. 736), suggesting that an alternative pathway must also exist. Each of the two rings of thiamin is formed separately as the esters 4-amino-5-hydroxy-methylpyrimidine diphosphate and 4-methyl-5-((i-hydroxyethyl) thiazole monophosphate. These precursors are joined with displacement of pyrophosphate to form thiamin monophosphate.92b In eukaryotes this is hydrolyzed to thiamin, then converted to thiamin diphosphate by transfer of a diphospho group from ATP.92b c In bacteria thiamin monophosphate is converted to the diphosphate by ATP and thiamin monophosphate kinase.92b...

Inositol monophosphatase catalyses the hydrolysis of a range of phosphate esters of inositol, and in so doing, participates in brain cell chemistry and is believed to be the target for lithium therapy. In the search for inhibitors of the enzyme, phosphate derivatives from 6-0-(2 -hydroxyethyl)cyclohexane-l,2,4,6-tetraol have been prepared, the racemic epoxide (26) acting as a key intermediate. The conversion of (26) into the racemic 1-phosphate (29) via (27) and (28) employed the steps indicated in Scheme 1. Further, the racemic alcohol (27) was... 

A convenient synthesis of diethyl (2-arylethenyl)phosphonates starts with readily available diethyl methylphosphonate this is converted into its carbanion (BuLi) and the latter acted upon by an appropriate aldehyde or ketone. The resultant (2-substituted-2-hydroxyethyl)phosphonate is phosphory-lated and, without isolation of the phosphate ester, a treatment with KOBu eliminates diethyl phosphate and yields the desired product Other diethyl (2,2-disubstituted-ethenyl)phosphonates have been prepared by the addition of organomagnesium-copper reagents to diethyl ethynylphos-phonate ... 

A calorimetric study of the hydrolysis of the esters (117 R = Me or Et) and of dimethyl 2-hydroxyethyl phosphate (and also of the phostonic esters (118 R = Me or Et) and comparison of their hydrolytic behaviour with that of dialkyl (2-hydroxyethyl)phosphonates) has been carried out so allowing a full analysis of thermodynamic aspects of the hydrolysis processes7 ... 

The control of particle size from 0.5 to 15 /an is possible by adding varying amounts of a protective colloid such as hydroxyethyl cellulose, an alkali salt of a maleate half ester, sodium phenyl phenolate, and/or a phosphate buffer at pH 6.9 [124].

Acrylic dental adhesives have been modified with a phosphate ester linkage by reaction of a glycidyl methacrylate or hydroxyethyl methacrylate with phosphorus oxychloride (158). One such product, a 3M Scotchbond, adheres to dentine as well as to tooth enamel. Adhesion to enamel can be improved in dental bonding cements by including an acryloxyalkyl- or acryloxyaryl acid phosphate component (159). Japanese products utilize an imsaturated phosphinic acid monomer to improve adhesion (160).
