Yv. Bilokin et al., STEREOSELECTIVE SYNTHESIS AND STRUCTURE DETERMINATION OF A NEW -TETRAHYDRO-2H-1,3-BENZOXAZOCINE-5-THIOCARBOXAMIDE, Heterocyclic communications, 4(2), 1998, pp. 169-170
Stereoselective one-step synthesis of a new -tetrahydro-2H-1,3-benzoxa
zocine-5-thiocarboxamide (3)under-bar from readily available 2-oxo-2H-
1-benzapyran-3-thio-carboxamide (2)under-bar has been described. The s
tructure of (3)under-bar has been elucidated by x-ray crystallography
and NMR spectroscopy. Using the thioamide group of (3)under-bar as a s
ynthon, compound (5)under-bar with 1,3-benzoxazocine, thiazole and cou
marin moieties has been synthesized.
