This 5-tert-butyl 3-ethyl 6,7-dihydro-1H-pyrazolo[4,3-c]pyridine-3,5(4H)-dicarboxylate features a sterically shielded tert-butyl group and ethyl ester handles, enabling stable incorporation into complex heterocyclic scaffolds. The dihydro-pyrazolopyridine core provides a rigid, electron-deficient platform for medicinal chemistry applications, facilitating efficient derivatization under standard conditions.
5-tert-Butyl 3-ethyl 6,7-dihydro-1H-pyrazolo[4,3-c]pyridine-3,5(4H)-dicarboxylate serves as a versatile scaffold for constructing biologically relevant heterocycles. Its electron-deficient pyrazolopyridine core enables reliable functionalization via Pd-catalyzed cross-coupling, while the tert-butyl and ethyl ester groups provide orthogonal reactivity and ease of purification. Bench-stable and compatible with standard synthetic workflows, it functions as a key intermediate in the development of kinase inhibitors and other medicinal chemistry leads.
