  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.

  Epoxidation of 1-Benzoyl-1,2,2a,3-tetrahydrobenz[cd]indole (4a) proceeded smoothly with metachloroperbenzoic acid with high exo diastereoselectivity (de = 96%) and chemical yield (97%). The basis for this selectivity was probed with substituent effects, and was extended to other oxidation media.

• Stereoselective Epoxidations and Electrophilic Additions to Partial Ergot Alkaloids and Conformationally-Fixed Styrenes. Experimental and Theoretical Modeling Evidence for the Importance of Torsional Steering as a Stereocontrol Element

  Partial ergot alkaloid substrates and related conformationally-fixed styrenes undergo epoxidation, osmium tetraoxide dihydroxylation, and hydrobromination with a level of stereoselectivity which cannot be explained by steric control but is consistent with electrophilic attack to minimize torsional strain. Force-field modeling is consistent with the importance of torsional steering as the dominant stereochemical control element.
