1H and 13C NMR chemical shifts have been determined and assigned based on PFG 1H, 13C HM...C, and HMBC experiments for 3-(4'-X-benzyl)-4-chromenones (Ia, X = CN and Ib, X = NO 2), 3-(4'-X-benzyl)-4-th

The arylmethylene of benzopyrane or benzothiopyrane 3,4 have been synthesized and condensed with hydrazine, guanidine and thiourea to yield pyrazole 5-8, aminopyrimidine 9,10 and thioxopyrimidine derivatives 11,12, respectively. Compounds 3 or 4 on treatment with malononitrile in the presence of ammonium acetate/acetic acid or in the presence of piperidine/ methanol to yield benzopyrano- and benzothiopyranopyridine 13,14 and benzopyrano- and benzothiopyrane 15,16, respectively. The oxirane of compound 3 is prepared and condensed with CS2 to yield the tricyclic system, thioxothienobenzopyrane 21. Ylidenemalononitrile for the ketone 1 and 2 are synthesized and condensed with aromatic aldehyde in presence of ammonium acetate/acetic acid to yield benzopyranopyridine and benzothiopyranopyridine derivatives 24,25, respectively, which are the isomer of compounds 13,14. Ylidenemalononitrile on condensation with phenylisothiocyanate yields benzo-pyrano- and benzothiopyranothioxopyridine 28,29, respectively.

3-Benzyl-4-chromones 6 and 7 and 3-benzyl-1-thio-4-chromones 8-10 have been synthesized by the piperidine-catalyzed reaction of chroman-4-one or 1-thio-chroman-4-one with benzaldehydes or by the double bond isomerization of the corresponding 3-benzylidene
