  Synthetic Studies toward the Partial Ergot Alkaloid LY228729, a Potent 5HT_1A Receptor Agonist

  摘要：

  Synthetic studies on LY228729 (3) afforded two innovative approaches for the construction of this class of partial ergoline 5HT(1a) receptor agonists. The first synthesis is based upon a diastereoselective epoxidation of racemic olefin 5, followed by ring opening and covalent resolution to furnish the key amino alcohol 8. Aziridination of amino alcohol 8, with subsequent tandem hydrogenolysis of the benzylic aziridine and auxiliary bonds, provided access to the optically active primary amine 13. A novel catalytic carboxamidation reaction installed the requisite side chain, Alternatively, the chiral pool was drawn upon for the single stereogenic center by virtue of L-tryptophan, albeit by a more circuitous route than expected. L-Tryptophan was differentially protected and reduced to the indoline diastereomers 26a,b which were separated by fractional crystallization. The two indoline diastereoisomers were independently cyclized by a Friedel-Crafts protocol, which under thermodynamic control afforded enantiomeric ketones 30a. The ketone was deoxygenated with a two-step reduction protocol to intersect the initial route and complete the second total synthesis. The two routes offer complementary access to this exciting class of partial ergot alkaloids.

  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.
