Platinum-oxide hydrogenation of 5-m-methoxyphenyl-2-methyl-9-oxomorphan (I) gave the 9α-hydroxy racemate (II) whose phenolic analogue (III) is a strong antinociceptive agent, fully supportive of morphine dependence in rhesus monkeys. The di-O-acetyl derivative (VI) of III was similar to III in its profile of activity. The diastereoisomer of III (VII), obtained by hydrogenation of the methobromide of
