Cyclic ketals and acetals (1,3-dioxolanes) substituted at positions 2 and 4 of the dioxolane ring, prepared by condensation of glycerol and ethylene glycol with aldehydes and ketones, had antimicrobial activity against Gram-positive and Gram-negative bacteria. This activity, which may be associated with the antiradical activity of the study compounds and(More)
The title compound, C(23)H(23)NO, is the product of a tandem transformation of the double Mannich base bis-(1-oxo-1,2,3,4-tertrahydro-2-naphtho-ylmeth-yl)amine hydro-chloride in HBr solution upon heating. The tetra-hydro-pyridine ring has a non-symmetrical half-chair conformation, whereas the cyclo-hexa-diene and cyclo-hexene rings adopt non-symmetrical(More)
The antibacterial activity of several groups of substituted mono- and diatomic phenols and their derivatives with various structural parameters was studied. An analysis of the results allowed the activity to be attributed to particular structural elements of the tested compounds.
In the title compound, C15H25NO2, all three six-membered rings adopt chair conformations. The cyclo-hexane and piperidine rings within the perhydro-isoquinoline are trans-trans fused. The N atom has a trigonal-pyramidal geometry (the sum of the bond angles is 328.0°). The methyl substituent occupies the sterically preferrable equatorial position. In the(More)
