(R)-3-methyl-1-((3aS,4S,6S,7aR)-3a,5,5-trimethylhexahydro-4,6-methanobenzo[d][1,3,2]dioxaborol-2-yl)butan-1-amine 2,2,2-trifluoroacetate; CAS No.: 179324-87-9; As a worldwide chemical supplier, ChemShuttle delivers boronate esters like this trifluoroacetate salt of a benzodioxaborolamine. The 3a,5,5-trimethylhexahydro framework provides steric protection for boron center reactivity. Our expertise in Suzuki-Miyaura precursor synthesis supports antibiotic ( -lactamase inhibitor) development. The chiral amine configuration (3aS,4S,6S,7aR) is achieved via enzymatic kinetic resolution, ensuring >99% ee for mechanism-based inhibition studies.
