Enantiopure 2,3-dihydro-4-pyridones as synthetic intermediates. Asymmetric syntheses of the quinolizidine alkaloids, (+)-myrtine, (-)-lasubine I, and (+)-subcosine I
摘要:
The first asymmetric syntheses of three quinolizidine alkaloids, (+)-myrtine, (-)-lasubine I, and (+)-subcosine I, were accomplished with a high degree of stereocontrol from readily available 4-methoxy-3-(triisopropylsilyl)pyridine in three, four, and five steps, respectively.
