Reactive dienophile. For a review of its Diels-Alder reactions, see: Org. React., 4, 1 (1948). For examples, see: Org. Synth. Coll., 3, 807 (1955); 4, 890 (1963). For reaction with Danishefsky's diene (1-Methoxy-3-trimethylsiloxy-1,3-butadiene, L14672), see: Org. Synth. Coll., 7, 312 (1990).
Also undergoes photochemical and thermal (2+2)-cycloadditions with alkenes. For reaction with 1-alkynes, see: Chem. Ber., 102, 3974 (1969).
For thermal (2+2)-cycloaddition with allene at high temperature, see: Org. Synth. Coll., 5, 459 (1973).
For use in combination with Urea hydrogen peroxide adduct, L13940, to generate peroxymaleic acid in epoxidation and Baeyer-Villiger reactions, see: Heterocycles, 36, 1075 (1993). Peroxymaleic acid can also be generated in situ from maleic anhydride and 30% H2O2 in NMP, and has been found to be a very effective oxidant for conversion of sulfides to sulfoxides. For a study of stoichiometric and catalytic oxidations with this system, see: J. Org. Chem., 61, 5693 (1996).

Библиография
A convenient method for the racemization of amino acids consists in heating in acetic acid with 0.05 equivalents of an aldehyde, such as salicylaldehyde: J. Org. Chem., 48, 843 (1983).
For a review of the use of circular dichroism studies of salicylidene derivatives of chiral amines, to establish their absolute configurations using the "salicylidene chirality rule", see: Chem. Rev., 83, 359 (1983).

Библиография
Strong organic acid, widely used in peptide synthesis to cleave N-Boc and t-butyl ester groups: Helv. Chim. Acta, 46, 870 (1963); see also Org. Synth. Coll., 9, 24, 268 (1998). For peptide reagents, seeAppendix 6. For selective cleavage of Boc in the presence of Cbz (Z), using 70% TFA in water, see:Liebigs Ann. Chem., 749, 90 (1971). For selective cleavage of benzyl, benzhydryl and trityl ethers in the presence of ester functions, see: Synthesis, 249 (1983).
Also catalyzes the cleavage of t-butyl groups from t-butylphenols, by reverse Friedel-Crafts reaction:Tetrahedron, 29, 4003 (1973). Similarly, hindered aryl ketones or aromatic carboxylic acids undergo deacylation: Synthesis, 979 (1985).
Carrying out the Curtius rearrangement of acyl azides in TFA leads directly to the trifluoroacetamide, which can be readily hydrolyzed to the free amine: Synthesis, 38 (1983).
With sodium nitrite, has been used for the cleavage of tosylhydrazones: Synthesis, 207 (1979); for nitrosation of anisole and derivatives, avoiding possible loss of the alkyl group: Acta Chem. Scand., 44, 152 (1990); for diazotization of weakly basic arylamines such as pentafluoroaniline or 3,5-dinitroaniline:Synthesis, 566 (1988); and in the presence of formamide, for deamination of arylamines: J. Chem. Soc., Perkin 1, 873 (1986).
For use of TFA as a catalyst in the Meerwein-Ponndorf-Verley reduction, see Aluminum isopropoxide, 14007. For use in the modification of the reducing properties of borohydride, see Sodium borohydride, 13432. For use in the ionic hydrogenation, see Triethylsilane, A10320.
