3D, 2D and 1D networks via N-H... O and N-H... N hydrogen bonding by the bis-amide analogues: Effect of chain lengths and odd-even spacers

The synthesis, crystal structures and hydrogen bonding networks of four members of the bis(pyridinecarboxamido)alkane and bis(pyridyl)alkanediamides series (1 ≈ n ; 8), where the amide moieties are separated by alkyl chain (-(CH2)n-) having even or odd number of -(CH2)-groups are explored and correlated with the previously reported structures. The odd members (n = odd) of both the series are found to adopt three-dimensional networks in contrast to the 1D or 2D structures of the even members (n = even). This odd-even effect on the dimensionality of the networks however disappears with increase in chain length.

Amido/imido alcohol/2-phenyl-3-hydroxyethylquinazolin-4 (3H) -one 1 on treatment with benzoic acid in the presence of cone. H2SO4 yields m-(aralkylamido/imidoalkyl/2-phenyl-3-ethyl-3H-4-oxoquinazolinyl) benzoic acids 2. The acid chloride of 2 on reaction with hydrazine hydrate affords m-(aralkylamido/imidoalkyl/2-phenyl-3-ethyl-3H-4-oxo-quinazolinyl) benzoic acid hydrazides 4 which on condensation with an aromatic aldehyde in acetic acid gives m-(aralkylamido/imidoalkyl/2-phenyl-3-ethyl-3H-4-oxo- quinazolinyl) benzoic acid hydrazones 5. Compounds 5 undergo cyclization with phenoxy acetic acid in the presence of thionyl chloride in dry benzene to furnish 1-[m-(aralkylamido/imidoalkyl/2-phenyl-3-ethyl-3H-4-oxo-quinazolinyl- benzamido)]-3-phenoxy-4-phenyl-2-azetidinones 6. The antiviral and antifungal activities of 6 have been reported.
