A synthetic approach to hydroindenic inotropic agents has been developed, s
tarting from enantiopure Hajos-Parrish (1), Hajos-Wiechert (2), and related
diketones. Their transformation: into C-l formyl derivatives and other sub
sequent synthetic targets is described. The results of the thermodynamic eq
uilibration between both epimers of each formyl derivative are analysed. Th
e inotropic activities of selected compounds on right and left atrial prepa
rations are also evaluated and discussed. (C) 1999 Elsevier Science Ltd. Al
