25. The 2- and 3-amines derived from electron-rich, fivemembered heteroaromatic compounds usually are highly unstable compounds, unless electron-withdrawing substituents are present, and therefore find uncommon use in synthetic annulation processes.
26. Tricycle 3a was originally reported in low yield via a troublesome six-step sequence from an N-(aryloxy)pyridinium salt, see: Abramovitch, R. A.; Inbasekaran, M. N.; Kato, S.; Radzikowska, T. A.; Tomask, P. J. Org. Chem. 1983, 48, 690.

43. (a) Unlike aryl azides, the (electron-rich) five-membered heteroaryl counterparts are usually hardly available from corresponding amines via diazonium salts,

46. 4 and finally evaporated in vacuo. Column chromatography of the crude on a Florisil column using PE as eluant isolated the title azide (0.71 mmol, 66%) as yellow thick oil. Physical and IR and NMR spectral data were fully consistent with those originally reported.

49. Reactions of enones with (benzothien-3-yl)iminophosphoranes bearing methyl substituent(s) on phosphorus were shown to form b-fused pyridines due to aza-Wittig electrocyclization along with those due to opposite regiochemistry, see ref. 10b,c.
50. Replacement of phenyl with electron-donating methyl group(s) on phosphorus could enhance the reactivity of previous (benzothien-2-yl)- and, especially, (benzothien-3yl)imino-phosphoranes with enones, see ref. 10b,c.
