The pyrano[4,3-b]pyrans (3a–3j) were synthesized utilizing inexpensive dehydroacetic acid and various sweet-smelling aldehydes in good yield and the structure was elucidated using different spectroscopic techniques. In vitro antimicrobial screening of 3a–
Synthesis of new dihydropyrazoles of designed curcumin analogues

Present work demonstrates a facile synthesis of a series of 20 dihydropyrazole derivatives from well designed curcumin analogues by reaction of chalcone derivatives with phenylhydrazine. All the synthesized compounds were characterized by spectroscopic (1H and 13C NMR, IR spectra), spectrometric (Mass spectra) data and elemental analysis. Synthesized dihydropyrazoles have diversity points on attached phenyl ring. Effect of substituent on reactivity was explained on the basis of electronic effect generated due to groups on phenyl ring. Presence of dd (double doublet) in 1H NMR spectrum of dihydropyrazoles was also explained due to presence of optically active carbon of pyrazole ring.
