A series of 1-methyl-7-(4-pyridyl)-5,6,7,8-tetrahydro-3(2H)-isoquinolinones and relatedcompounds were synthesized and evaluated for positive inotropic activity. Most members of this series exerted a dose-dependent increase in myocardial contractility in the dog acute heart failure model, whereas they caused only slight changes in heart rate and blood pressure. Several derivatives, especially those
A carbon–carbon bond was formed at the β-position of cyclicketones in a one-pot manner by oxidation with N-tert-butylbenzenesulfinimidoyl chloride, followed by the reaction of malonic acid esters or potassium cyanide.
Complexes of rare earth elements with 2-acetylcyclohexanone have been reported earlier. Complexes with 2-Butyrylcyclohexanone are prepared. These are characterised by u.v. and i.r. spectral data. Successive stability constant values are reported.
