Abstract
A process for preparing a chiral tetracyclic compound of formula (1), wherein R is hydrogen or a C1-C6-alkyl group and Z is oxygen, sulfur or -CH=CH-, the compounds having uses as dopamine agonists. The process involves reacting a chiral starting material and subsequent chiral intermediates in a series of chirality-preserving synthetic reactions.
