용도

2,5-Hexanedione is used as a reagent in the preparation of trans-2,5-dimethylpyrrolidine. It is also used in the synthesis of 2,5-dimethylpyrroles. Further, it plays an important role as a reagent used for the protection of amino groups in amino sugars and nucleosides. In addition to this, it is used in the preparation of five-membered heterocycles like indane-type and benzannulated systems. It is also employed as a precursor in Diels-alder cycloaddition reactions.

참고

Incompatible with strong oxidizing agents, strong bases, metals and strong reducing agents.

참조 문헌

Primary amines can be protected by conversion to 2,5-dimethylpyrroles, from which they can be released by reaction with hydroxylamine hydrochloride: J. Chem. Soc., Perkin 1, 2801 (1984). The method has been found useful for protecting amino sugars in oligosaccharide synthesis: J. Org. Chem., 63, 4570 (1998), and also in the protection of an arylamine during Cu(I) promoted methoxylation of a ring bromo or iodo substituent; Synthesis, 1599 (1998).
