accounted for by a scheme in which gold(III) acts as an electrophile to give an organometallic adduct; this breaks down by heterolysis of the C–Au bond, accompanied by competition between rearrangement of a neighbouring substituent and uptake of a nucleophile. In all cases a close similarity was observed with the products obtained from oxidations by thallium(III) and lead(IV); where divergences occur
Lithiated ambident anions derivedfrom (1-alkyl-2-propenyl)- or (1-phenyl-2-propenyl)-pentamethyl phosphoric triamides undergo regioselectively γ-reaction with various alkylating reagents and isobutyraldehyde. Further hydrolysis of adducts releases the ketone under acid conditions. Number of synthetic applications clearly show the ketone homoenolate behaviour of these new carbanions.

The low-temperature Grignardreaction of mixed carboxylic anhydrides derived from acid chlorides and o-anisic acid to the general synthesis of keto esters is demonstrated for compounds 1–6, although, some limitations on substrate and Grignardreagent species are also encountered; attempts in the oxa series 2 are unsuccessful, and reaction with ω-phenylpropyl Grignard species for 1 and 4 shows a drastic

The present invention relates generally to methods of diagnosis, evaluation and treatment of coronary artery disease in mammals using substituted catecholamines and compounds therefore. It also relates to the preparation, use and administration of these compounds which are useful in the diagnosis, evaluation and treatment of coronary artery disease by means of a feedback controlled drug delivery system that delivers exercise simulating agents which are capable of eliciting acute responses similar to those elicited by aerobic exercise.
