4,6-Methano-1,3,2-benzodioxaborole-2-methanamine, hexahydro-3a,8,8-trimethyl-alpha-(2-methylpropyl)-, (alphaR,3aS,4S,6S,7aR)-, 2,2,2-trifluoroacetate (1:1)

This compound is a highly functionalized, chiral boron-containing heterocycle, present as a trifluoroacetate salt (1:1). Structurally, it features a benzodioxaborole core, a primary amine side chain, and multiple stereogenic centers, indicating deliberate asymmetric synthesis. The boron heterocycle and protected, rigid bicyclic framework are characteristic of advanced synthetic building blocks used in medicinal chemistry and complex API synthesis, particularly where enzyme binding, stereochemical precision, or boron-based pharmacophores are required. The directory classifies it as a under development API with a synthetic source/manufacturing origin. Other names for this substance include Bortezomib Impurity 38 and (R)-BoroLeu-(+)-pinanediol-trifluoroacetate. Its PubChem CID is 44244713.
