Applicazioni

Chloromethyl pivalate acts as an intermediate in the synthesis of active pharmaceutical ingredients. It is also involved in the acylation reaction with 9-(2-phosphonylmethoxyethyl)adenine. It serves as a protecting reagent used for the N-protection of amines. It is also employed in the preparation of pivaloyloxy methyl ester of ofloxacin as a prodrug. Further, it is used to prepare sulbactam pivoxil by reaction with sodium salt of sulbactam. In addition to this, it is used as a reagent during the synthesis of an isoindoline-annulated and continuous-flow organic synthesis.

Note

Incompatible with strong oxidizing agents.

Letteratura

Reagent for the N-protection of amines, e.g. adenine in the presence of K2CO3 in DMF, as pivaloyloxymethyl (Pom) derivatives, which have been found useful in the synthesis of sensitive nucleosides. The Pom group is cleaved in mild base, e.g. methanolic ammonia: J. Am. Chem. Soc., 89, 5439 (1967).
