Potassium ((tert-butoxycarbonyl((2S,3S)-1-methoxy-3-methyl-1-oxopentan-2-yl)amino)methyl)trifluoroborate by Molecular Depot is a potassium (tert-butoxycarbonylamino)methyltrifluoroborate bearing a protected isoleucine methyl ester, with defined (2S,3S) stereochemistry. An aminomethyltrifluoroborate carries a protected amine next to the boron, which lets an aminomethyl group be installed by cross-coupling rather than built up in steps. It is used as a coupling partner in Suzuki-Miyaura reactions to install protected aminomethyl groups and in peptidomimetic and medicinal chemistry synthesis. Each unit contains 50 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
