Hydride Reductions of 1-Phenyl-1-nonen-3 -one: Mass Spectrometry of 1-Phenyl-1-nonen-3-ols and Relative Stereochemistry of the Diastereoisomeric 4-Dimethylaminomethyl-1-Phenyl-1-nonen-3-ols
Searching for novel antiobesity agents, a series of cannabinoid LH21 and of Rimonabant-fatty acid amide analogues have been prepared. Synthesis of pyrazoles 2a–2c was achieved by a two steps simple methodology via α,β-unsaturated ketones. Carboxamides 8a–8h were obtained in good yields from esters 7a–7c by a one-pot procedure which takes place under mild conditions. New compounds have been evaluated in

The mass spectra of a series of nuclear substitutedstyryl ketones with the structureand several relaTed compounds have been determined. The major fragmentation pathways include such processes as an aromatic substitution reaction occurring in the molecular ion as well as the McLafferty rearrangement. Only one of the two possible α-cleavages at the carbonyl function was observed. The major decomposition
