Patent number: 11764043Abstract: Isobaric mass spectrometry tags (e.g., TMT) are susceptible to ratio compression, which arises from the co-isolation and co-fragmentation of interfering species that also contribute to the final reporter ion ratios. Additional stages of ion activation/transformation (e.g., MSn and PTR) have been shown to decrease ratio compression. Embodiments of the present invention include a mass spectrometry cleavable moiety on the isobaric mass tags. The cleavable moiety allows for a predictable mass loss, and results in an improved tag reporter ion purity.Type: GrantFiled: July 6, 2018Date of Patent: September 19, 2023Inventors: Michael W.

The critical elements of the method are: a non-racemic chiral tertiary-amine-containing catalyst; a substrate selected from the group consisting of ketones, aldehydes, thioketones, thioaldehydes, imines and hydrazones; and a silyl cyanide, e.g., trimethylsilyl cyanide. In preferred embodiments, the substrate is a ketone or aldehyde. A preferred embodiment of the present invention relates to practicing the method in a halocarbon solvent, e.g., chloroform. Another preferred embodiment of the present invention relates to practicing the method in an ester solvent, e.g., ethyl acetate. In certain embodiments, the methods of the present invention produce a silyl cyanohydrin with an enantiomeric excess greater than about 80%.Type: ApplicationFiled: February 5, 2003Publication date: December 25, 2003Inventors: Li Deng, Shi-Kai Tian
