Abstract

Chemistry. 2 '-Hydroxy-, 4'-Hydroxy-, 5 '-Hydroxy-, 6'-Hydroxy-, and 7'-Hydroxypropranolol (la, cf). Five of the isomers of hydroxypropranolol were prepared from the corresponding methoxynaphthols (h, cf) by the route shown in Scheme I. Compound 2a was prepared from 2-methoxy-1-naphthaldehyde (5, Scheme 11) via a Baeyer-Villigerl'rearrangement using m- chloroperbenzoic acid to form 6, which upon hydrolysis with aqueous sodium hydroxide ...
