homologation of vinyltriflates and bromides for the synthesis of homoallylic nitro products is described. This palladium-catalyzed double coupling of nitromethane exploits the anion stabilizing and leaving group properties of nitromethane, generating the homo allyl nitro products via a tandem cross-coupling/π-allylation sequence. The resultant process provides a mild and convenient entry to nitroethylated
The present invention is concerned with compounds of formula (I) ##STR1## wherein R.sup.1 is hydrogen or C.sub.1-4 alkoxy; R.sub.2 is carbonyl, hydroxymethylene, or methylene; and R.sub.3 is hydrogen or hydroxy; and salts thereof, provided that when R.sub.1 is hydrogen and R.sub.2 is carbonyl, R.sub.3 is not hydroxy, with processes for preparing same and with their use in medicine for the treatment of hypertension.
