## Abstract Ibogamine (11b) was synthesized starting from the vinyl sulfone 3. Addition of organocuprate reagents to 3 furnished 2a–d with high stereoselectivity. Only products from the syn addition of the cuprate reagents could be detected. Functional group transformations provided 7a,b the key in

Compound 7, a precursor in the synthesis of 4-methoxybalbergione, was prepared from compound 6 with an enantiomeric excess of 17 to 94% by asymmetric catalytic hydrogenation using rhodium or ruthenium chiral complexes. The best hydrogenation results were obtained using [Rh((S,S)-bdpp)(NBD)1 Cl04, an
