2-Hydroxyethyl ester

An efficient one-pot synthesis of isoxazolines, using soluble polymer-supported acrylate has been described (174). Thus, the addition of 1,4-benzenedicarbonitrile N,N -dioxide (generated from N, N -dihydroxy-1,4-benzenedicarboximidoy 1 dichloride) to polyethylene glycol-supported 2-propenoic acid 2-hydroxyethyl ester 32 (P = polyethylene glycol support) followed by cleavage of the bond with the support gave 3,3/-(l,4-phenylene)bis[4,5-dihydro-5-isoxazolecarboxylic acid] di-Me ester (33) in 97% yield. 

For example, a proline-based chiral ligand was attached to a vinyl-substituted monomer (Fig. 42.15) by reacting vinylbenzoyl chloride with the amine functionality of the ligand [106]. As mentioned previously, the apolar Merrifield resin as a support is not swollen in polar solvents. Hence, in order to match the polarity of the resin with that of the typically used substrates in enantioselective hydrogenation, the functionalized monomer was copolymerized with polar units of methacrylic acid 2-hydroxyethyl ester. 

Ethyl 6-hydroxy-l-oxo-l//-pyrimido[l,2-a]quinoline-2-carboxylate was prepared from the 2-carboxylic acid in boiling ethanol in the presence of 3% hydrogen chloride for 4 h (77GEP2628751,77USP4031217). Heating ethyl 6-methoxy-l-oxo-l//-pyrimido[l,2-a]quinoline-2-carboxylate in ethylene glycol in the presence of triethylamine for 6 h yielded the 2-hydroxyethyl ester (75GEP2513930). 

For example, EC yields polymers containing blocks of poly-ethers and polycarbonates. due to the partial elimination of C02 [246], while its hydrolysis produces high-purity 1,2-diols. Furthermore, CCs react readily with carboxylic acids to form 2-hydroxyethyl esters [177, 247, 248].

The reaction of 3 in aqueous acid results in the formation of the 2-hydroxyethyl ester of diohloroacetic acid, the structure of which is given by either or both of formulae 4 and 5. Depending on which of these formulae is considered, the reaction could be described either as hydrolysis or as hydration of 3.

Hydroxyethyl esters were prepared from carboxylic acids and ethylene oxide in the presence of DBU (73JAP(K)37003). 

Yoda et al. [58] assumed that the metal compounds induce a positive charge on the carbonyl carbon atom of the ester group of DMT, facilitating attack of the glycol. In model reactions, catalysts (M) more strongly activated 2-hydroxyethyl esters, perhaps through formation of a chelate [57]...

Pyrolysis process for poly(2-hydroxyethyl methacrylate) occurs similarly to that for other methacrylic acid esters. The formation of 2-methyl-2-propenoic acid 2-hydroxyethyl ester, the monomer, shows that unzipping is a significant part of the process. Some other compounds in the pyrolysate also are generated from the polymer cleavage, such compounds including 2-methyl-2-propenoic acid ethenyl ester, propanoic acid, 2-methyl-2-propenoic acid, ethanol, etc. On the other hand, some compounds are not expected in the pyrolysate and they can be impurities or additives. Examples of such compounds are the hydrocarbons (undecene, dodecane, 1-dodecene, etc.), the esters of ethylene diol and the free 1,2-ethandiol, etc. The initiator AIBN and its decomposition products 2-methyl-2-propenenitrile and 2-methylpropanenitrile identified in the pyrolysate show that the polymer was obtained using AIBN as initiator. 

Besides the benzyl hydrazide linker 44, Wieland et al. introduced a 2,2-diphenyl-2-hydroxyethyl-ester derived resin [58], This linker type can be activated by acid-catalyzed dehydration (aq. TFA) to give the reactive enol ester 51, which affords amides 53 upon treatment with amines (Scheme 16.12).
