A transketolase-based synthesis of (+)-exo-brevicomin
摘要:
The naturally occurring beetle pheromone (+)-exo-brevicomin was synthesized by a strategy combining chemical and enzymatic steps. The commercially available enzyme transketolase (EC 2.2.1.1) catalyzed the condensation of beta-hydroxypyruvic acid and 2-hydroxybutyraldehyde to furnish the central intermediate in the sequence, optically active hydroxyketone 5. A short sequence converted ketose 5 to protected aldose 8. Wittig extension of the aldehyde followed by hydrogenation and ketal hydrolysis generated the title compound.
