The synthesis of (+)- and (−)-1-benzoyl-1,2,2a,3,4,5-hexahydrobenz[cd]indol-4-amine, and preparation of LY228729.
摘要:
Racemic epoxide 5 was reacted with S-Phenylethylamine to afford diastereomers 6 and 7, from which amino alcohol 6 could be isolated directly. Aziridine formation and tandem-hydrogenolysis provided optically pure primary amine 2 (31% from racemic 4), which was further elaborated to LY228729 (15), an interesting 5HT1a receptor agonist.
