A Diastereoselective Synthesis oftrans/cisOctahydronaphthoquinolizine
摘要:
The tetracyclic system of 2,3,6,7,7a,8,12b,12c-octahydro-1H,5H-naphtho[1,2,3,ij]quinolizine with trans/cis fusions of the B/D and B/C rings has been diastereospecifically synthesized in nine steps and in 23% total yield.

Unsubstituted and methoxy-substituted octahydronaphthoquinolizines, examples of newtetracyclicringsystem, have been synthesized in three steps from corresponding 2-tetralones. The various diastereomers of each OHNQ have been separated and characterized by X-ray crystallography and NMR spectroscopy. These compounds have been shown to have activity at selected neurorecepter binding sites.
