摘要

Reactive iridoid derivates represented by the following general formula (wherein R represents a hydrogen atom, an alkyl group with 1 to 5 carbon atoms, an acyl group with 2 to 6 C atoms, an unsubstituted aralkyl group with 7 to 12 C atoms, a methanesulfonyl- or toluenesulfnyl group, a benzoyl-, a preferable para-substituted nitrobenzoyl- or chlorobenzoyl group, or a tetrahydropyranyl group), process for the manufacture of said derivates starting from catapol as an easily obtainable natural substance and use of said derivates as intermediates for the manufacture of prostanoids.
