Process for the preparation of hydroxyadamantanone derivatives
 The invented process produces a corresponding 5-hydroxy-2-adamantanone derivative by allowing a 2-adamantanone derivative of the following formula (1): ##STR1## wherein each of R.sup.a, R.sup.b, and R.sup.c is, identical to or different from one another, a hydrogen atom, a halogen atom, an alkyl group, a hydroxyl group which may be protected by a protective group, a hydroxymethyl group which may be protected by a protective group, an amino group which may be protected by a protective group, a carboxyl group which may be protected by a protective group, or a nitro group, and of carbon atoms constituting an adamantane skeleton, the other carbon atoms than carbon atoms at bridgehead positions and at a bonding position of an oxo group may have a substituent, to react with oxygen in the presence of N-hydroxyphthalimide or another imide compound, a vanadium compound, and a manganese compound.
