Abstract

PROBLEM TO BE SOLVED: To obtain an new derivative high in affinity for central nerve-type prostacycline receptor subtype (IP2 ) and useful as a therapeutic agent for central nervous system-related diseases or also as a probe for examining and diagnosing brain central nerve activity and its abnormalities. SOLUTION: This new compound is a 15-deoxy-isocarbacycline derivative of formula I (R is a 1-6C hydrocarbon chain) (e.g. 15-deoxy-16-m-tolyl-17,18,19,20- tetranorisocarbacycline). The objective derivative is obtained by the following process: an aldehyde compound of formula II (triphenyl phosphoranylidene) is reacted with acetaldehyde followed by methyl chloroformate and then a disulfone compound; thereafter an elimination reaction is carried out to form a carbacycline derivative which, in turn, is hydrolyzed.
