Alkyl ethoxy carboxylates or carboxylated nonionics, as they are also called, are well known specialty nonionics which can be used as nonionics at neutral pH or as anionics at high pH [19]. Recently amide analogs of these materials have been developed [20], called amide ether carboxylates (Fig. 16). The standard method for making carboxylated nonionics is adding sodium chloroacetate to an ethoxylated alcohol, while the amide analog is made in a similar fashion from an ethoxylated monoethanolamide.

The Friedlander condensation of 2,6-diaminopyridine-3,5-dicarbaldehyde (393) with various ketones has been reported (77JOC3410). Reaction of the aldehyde with acetophenone, with deoxybenzoin and with a-tetralone generates the 5,10-dihydro-l,9,10-anthyridine derivatives (394 R = H), (394 R = Ph) and (395) respectively, whilst with acenaphthenone the nonacyclic anthyridine (396) is obtained. The condensation between 2-amino-3-ethoxy-carbonyI-l,8-naphthyridine (225) and alkyl carboxylates under basic conditions produces 4-hydroxy-1,9,10-anthyridin-2-ones (397) (79BAP571). 

Phenanthridones and benzophenanthridones undergo ready alkylation on treatment with dialkyl sulfates in alkali.113, 126 As in the case of other, similar, ambident nucleophiles, V-alkylation normally predominates, although with diethyl sulfate 2-nitrophenanthridone gives a significant amount (27%) of 6-ethoxy-2-nitrophenanthri-dine,126 and, more recently, O-methylation has been observed in the reactions between both the methyl ester and the pyrrolidine amide of phenanthridone-4-carboxylic acid with methyl iodide in the presence... 

Condensation of 1- and /V(6)-alkyl and unsubstituted 6-aminoindazoles with diethyl ethoxy-methylenemalonate in Dowtherm A at elevated temperature gave the ethyl 6,9-dihydro-9-oxo-pyrazolo[3,4 /]quinoline-8-carboxylates (88) (Equation (49)) <83JHC1351>. The 6-ethyl-8-carboxylic acid derivative is a potent antibacterial agent. 

Metallated 1-ethoxy-1,3-dienes 697 and 712, obtained from the corresponding acetals by means of the LICKOR base, have been treated with alkyl halides, epoxides, carbonyl compounds, carbon dioxide and carboxylic esters affording ( )-l-substituted 1-ethoxy-1,3-dienes and, after hydrolysis, a,P-unsaturated carbonyl compounds1007-1010 (Scheme 186). Intermediates 697 and 712 have been transformed into the corresponding vinyl stan-nanes, which were submitted to Stille couplings with iodobenzene and benzoyl chloride823. 

The acylation of phosphonic carbanions with carboxylic esters is a procedure which has received widespread attention and employed to prepare the protected dimethyl (3,4-dihydroxy-2-oxobutyl)phosphonate 608 and dimethyl [(35)-3-methyl-2-oxo-5-octynyljphosphonate (609), intermediates required in natural product synthesis d An example of intramolecular acylation is the formation of 610 by the action of potassium tert-butoxide on ethyl 2-[(ethoxy)methylphosphinoyl]benzoate d. Acylations of lithiated phosphonoyl carbanions provide dialkyl [(l-formyl)alkyl]phosphonates d ...

In our system, the acid chloride as the acylating agent was not applicable due to the basic conditions of the proposed transformation and the internal free nitrogen of the piperidyl moiety. However, the trioxifene acylation was adapted by preparing the phenyl ester of 5. Therefore, the required phenyl 4-[2-(l-piperidinyl)ethoxy]benzoate (9) was prepared by alkylating methyl 4-hydroxybenzoate with 2-(l-piperidinyl)ethyl chloride (6). Hydrolysis of the methyl ester provided the carboxylic acid that was converted to the acid chloride (8) using SOCI2 in a mixture of 1,2-dichloroethane and toluene. Acid chloride 8 was then reacted with sodium phenolate to provide 9 as a stable crystalline solid in 64% overall yield from the carboxylic acid.
