Methylal acid benzyl ester

Reaction of carboxylate ion with nitrophenyl sulfites gives the carboxylate -nitrophenyl esters. If the -nitrophenyl sulfite is unsymmethcal (02NCgH40S(0)0R, where R is ethyl or phenyl), carboxylate attacks the -nitrophenyl side (69). Some amino acids react with methyl and benzyl sulfites in the presence of -toluenesulfonic acid to give methyl and benzyl esters of the amino acids as -toluenesulfonate salts (70). With alcohols, the conversion of henzil to a monoacetal upon addition of sulfuric acid to the henzil in methanol and dimethyl sulfite proceeds in high yield (71).

The methyl and benzyl esters of proline were also used as chiral auxiliaries in respective acrylamides, but the isoxazoline cycloadducts were obtained with only poor to modest stereoselectivity (189,190). The related indoline-2-carboxylic acid derivative 33, however, showed excellent ability to direct nitrile oxide attack, favoring one rotamer (Scheme 6.37), and thereby leading to 3-phenylisoxazoline-5-carboxamide...

The carboxy group is usually protected as a methyl or benzyl ester by reaction with an alcohol and an acid. 

AUcyl esters (e.g., methyl, ethyl, benzyl esters) are usually stable toward amines and, thus, are used as protecting groups. Some anecdotic examples of amide bond formation with aUcyl esters, however, are reported in the literature. High reaction temperature, addition of a Lewis acid (52), or use of organoaluminium species generated from DIBAL-H-H2NR (53) can enable these reactions. Saturated ammonia in methanol can also react with... 

In the case of N-alkykarbamic acid benzyl esters, too, those homologues in which only one methyl group was substituted on the N-atom were the most active. An alkyl substituent with longer chain reduced the herbicidal action.

Some simple esters of proline have found applications as auxiliaries. Thus, the methyl ester 2 was used to form chiral amides for hydride reductions (Section D.2.3.3.). Methyl and benzyl esters 2 and 3 form amides with various types of carboxylic acids which are used in the addition of zinc or titanium species to carbonyl groups (Section D. 1.3.3.3 ). The amide of (S)-proline [(S)-4] has been used in enantioselective Michael additions (Section D.I.5.8.), and (5 )-Ar-tri-fluoroacetylproline [(.S)-5] is the only simple A-acyl derivative used as an auxiliary (Section D.l.1.2.2,).
