A series of novel ethyl 7,9-diaryl-1,4-diazaspiro[4.5]dec-9-ene-6-carboxylates was synthesized by the reaction of ethyl 4,6-diaryl-2-oxocyclohex-3-ene-1-carboxylates with ethylenediamine in the presence of p-toluenesulfonic acid without a solvent under focused microwave irradiation. The title compounds were screened for their antimicrobial activities against a spectrum of clinically isolated microorganisms.

Abstractmagnified image We report an efficient and new method of synthesis of 2‐amino‐5,6‐dihydro‐5,7‐diarylquinazolin‐4‐ols by the reaction of substituted cyclohexenones with guanidine hydrochloride in presence of NaOEt. The reactions are with 50–72% yield. All the synthesized compounds are characterized using IR, NMR and CHN analysis. J. Heterocyclic Chem., (2009).
