Six compounds 7,9-diphenyl-1,4-dioxa-8-azaspiro[4.5]decane 1-6 have been synthesized by Mannich reaction and cyclo condensation. The structures and stereochemistry established by IR, NMR studies. The purities were checked by elemental analysis. The synthesized compounds 1-6 adopt chair conformation with equatorial orientation of the aryl groups. All the compounds were screened for their antibacterial activity against Proteus mirabilis, Klebsiella oxytoca, Staphylococcus aureus and Salmonella paratyphi. The compound 5 exhibited excellent in vitro antibacterial activity in all species.

1-Hydroxy-2,6-diaryl-4-piperidone ketal derivatives, such as the compound of formula I STR1 wherein Ar1 and Ar2 are each phenyl, R1 to R6 are all hydrogen, X1 and X2 are each --O-- and T is a direct bond, are novel compounds and are effective process stabilizers, such as polypropylene, for polymers processed at elevated tempertures providing both good melt flow stabilization and good resistance against discoloration during said processing.
