tert-Butyl 4-(aminocarbothioyl)tetrahydropyridine-1(2H)-carboxylate is used as a versatile intermediate in the synthesis of pharmaceutical compounds, particularly for constructing heterocyclic systems via the reactive aminothiocarbonyl (thioamide) group at the 4-position of the N-Boc-protected 1,2,3,6-tetrahydropyridine ring. This structure facilitates reactions such as thiazole formation with α-haloketones or Gewald-type condensations, enabling the development of biologically active nitrogen- and sulfur-containing heterocycles. It is valuable in medicinal chemistry for creating analogs targeting central nervous system disorders, antimicrobials, and anti-inflammatory agents. The Boc protecting group allows selective deprotection and further functionalization, supporting combinatorial chemistry and high-throughput screening for drug candidates.
