TCI B6776 (CAS 1402232-83-0) is a Boc-protected fluorinated spiro[piperidine-quinoline] building block designed for medicinal chemistry programs. Its rigid, sp3-rich spirocyclic core offers three-dimensional character that is valuable for exploring new chemical space. The free anilinic nitrogen provides a convenient handle for acylation, sulfonylation, or alkylation during library synthesis. AMI Scientific offers this TCI reagent in a 100 mg pack size for research-scale synthesis.
