, p. 1075 - 1077 (2007/10/02)
3-Benzal-2,3-dihydro-4H-1-benzopyran-4-ones (8-14) have been synthesizedin good yields by a novel one-pot method involving condensation of hydroxyacetophenones with aromatic aldehydes.The reaction is general and has a biogenetic significance.
NOVEL ONE POT CONVENIENT SYNTHESIS OF 3- BENZYLIDENE-2-PHENYL-2,3-DIHYDRO-4H-1-BENZOPYRAN-4-ONES

3-Benzylideneflavanones (3-benzylideneflavanone, 6-hydroxy-3-benzyl deneflavanone, 7-methoxy-3-benzylideneflavanone) were treated with hydrazine and methylhydrazine.As a result some not yet described compounds were obtained containing a condensed system of chromanone and pyrazoline.As a result of reaction with diazomethane, on the other hand, also not yet described spirane compounds were obtained.
