The present invention provides aminoalkoxy carbazole derivatives, and more specifically, provides compounds of formula (I)
wherein R1, R2, R3, R4, R8 and R9 are described herein. These compounds are 5-HT ligands, and are useful for treating diseases wherein modulation of 5-HT activity is desired.
Functionalized chiral carbazolones with α‐quaternary carbon centers are formed through the ligand‐controlled Pd‐catalyzed enantioselective decarboxylative allylicalkylation of carbazolones (see scheme). This catalyticasymmetric reaction was employed as the key step in the total synthesis of aspidospermidine and (+)‐kopsihainanine A.
