Reported herein is the first visible-light-induced formation of alkoxyl radicals from N-alkoxyphthalimides, and the Hantzsch ester as the reductant is crucial for the reaction. The selective hydrogen atom abstraction by the alkoxyl radical enables C(sp3)-H allylation and alkenylation reactions under mild reaction conditions at room temperature. Broad substrate variations, including a structurally complexed steroid, undergo the C(sp3)-H functionalization reaction effectively with high regio- and chemoselectivity.

, (2008/06/13)
Substituted phenoxy-aminopropanols of the formula STR1 wherein R is a branched-chain alkyl of 3 or 4 carbon atoms, R 1 is hydrogen, halogen or lower alkyl and R 2 and R 3, independently, are hydrogen, halogen, lower alkyl, lower alkoxy or lower alkylthio, and pharmaceutically acceptable acid addition salts thereof, are described. A process for their preparation, as well as pharmaceutical preparations containing them are also described. The compounds of formula I and their salts possess cardioselective β-adrenergic blocking activity and antihypertensive activity.
