Abstract

PURPOSE: To prepare the title compound easily, by eliminating sulfonic acid from porfiromycins (novel compounds).
CONSTITUTION: The title compound of formula I is prepared by eliminating sulfonic acid from a novel compound of formula II (X is alkoxy or NH2; R is sulfonyl). The reaction is carried out in a solvent such as ether, in the presence of a base (pref. potassium-t-butoxide, etc.). The amounts of the solvent and the base are 1W100 moles each per 1 mole of the compound II, at 0W80°C. The compound II can be prepared by converting a compound IV to a compound III by lithium aluminum hydride process, etc., and treating the compound III with a sulfonylating agent.
