Abstract
A process for the preparation of a two-functional-group-containing terpenoid having the general formula: ##STR1## in which n is an integer of from 1 to 5, R represents a hydroxymethyl, formyl or carboxyl group, and A represents the hydrogen atom, or a 2-tetrahydropyranyl, benzyl, methoxymethol or methoxyethoxymethyl group comprising the oxidation with a microorganism belonging to the genus Nocardia. Some of the terpenoids are of value as anti-ulcer agents, while others are useful as intermediates.
