Cis-3-(tert-butoxycarbonylamino) cyclobutanecarboxylic acid is an important organic reagent that can be used as a building block for the synthesis of many organic compounds. Such as tert-Butyl ((1R,3s)-3-((2-(2-((2S,3S)-1-methyl-5-oxo-2-(pyridine-3-yl)pyrrolidine-3- carboxamide)ethoxy)ethyl)carbamoyl)cyclobutyl)carbamate which could be used to synthesize heterobifunctional molecules, referred to as cytotoxicity targeting chimeras (CyTaCs) or antibody recruiting molecules (ARMs) that are able to simultaneously bind a target cell-surface protein as well as an exogenous antibody protein.
