Application

Di-tert-butyl dicarbonate (Boc anhydride) can be used:
  • As a reagent to introduce Boc protecting group for the amine functionalities.
  • To prepare tert-butyl ethers and Boc-alcohols in presence of Lewis acid catalyst.
  • As a carboxylating agent for the preparation of a variety of tert-butyl carboxylates.
  • For the conversion of amines to corresponding isocyanates, carbamates and urea derivatives.
  • As a coupling reagent for anchoring various carboxylic acids to hydroxymethylated resins.
  • To synthesize quinolinones and 2-(pseudo)haloquinolines from 2-alkenylanilines in presence of DMAP as a catalyst.

Automated Boc protection and deprotection can be done using Synple Automated Synthesis Platform (SYNPLE-SC002), Boc protection cartridges ((SYNPLE-B001), (SYNPLE-B002), and Boc deprotection cartridges (SYNPLE-B011)
Reagent for the introduction of the Boc protecting group.
