When the aromatic aldehyde contained an ortho hydroxyl or amino group, cyclization to the coumarins or quinolines, respectively, occurred. Attempts to condense ethyl 2- and 4-pyridylacetate (either as the free base or as the methiodide) with phenyl methyl ketone or with o-hydroxyphenyl methyl ketone were unsuccessful. However, the methiodide of the 4-isomer yielded a quinoline when treated with o-aminophenyl methyl ketone.

Methyl-8-formylBIPS (71, Z = O) was condensed with amines to give in 36-61% yields the 8-anils (Z = N-R) (R = benzyl and 4-X-phenyl, [X = acetyl, nitro, and methyl]), and with aldehydes to give in 62-76% yields the 8-styryl ketones (Z=CH-R ) (R = methyl, phenyl, and 2-hydroxyphenyl). The styryl ketones were shown by their NMR spectra to be the cis isomers. Of the anils, only the 4-nitrophenyl...
