Komplexe Cyclisierung der Aminoxide isomerer Perhydrochinolizin-1-ole
摘要:
Bei der Oxidation der Perhydrochinolizin-1-ole 1 und 2 entstehen nicht nur die Aminoxide 4 und 5,sondern unter Stickstoff-Inversion auch 6. Die Strukturen werden spektroskopisch gesichert。4 和 6 geben die entsprechenden 硼甜菜碱 7 和 8。

The synthesis of a series of azabicyclic indole esters is described and their potency reported as 5-HT4 receptorantagonists. Optimization of the most potent compound (19) by preparing the corresponding oxazino[3,2-a]indole ester afforded 34, which had a pIC50 of 9.5 in the guinea pig distal colon longitudinal muscle myenteric plexus preparation.

A concise synthesis of (±) and a total synthesis of (+)-epiquinamide

A total synthesis of the quinolizidine alkaloid (+)-epiquinamide 1 has been achieved starting from (-)-pipecolinic acid 3. The key step is the highly diastereoselective addition of a TBDMS-protected propargyl alcohol to a chiral aldehyde derived from 3 to give erythro alkynol 19, which is then easily transformed into the desired bicyclic skeleton.
