Synthetic Applications of Alkyl (E)-2-Tributylstannyl-2-alkenoates: Selective Synthesis of (S)-1-Methylbutyl (E)-2-Methyl-2-pentenoate, an Aggregation Pheromone Component ofRhyzopertha dominicaandProstephanus truncatus
摘要:
Stereoisomerically pure (S)-1-methylbutyl (E)-2-methyl-2-pentenoate (dominicalure-1), (S)(E)-11, an aggregation pheromone component for the lesser and the greater grain borers, has been efficiently synthesized from the main product of the palladium-catalyzed reaction between ethyl 2-pentynoate, 1a, and Bu3SnH, i.e. ethyl (E)-2-tributylstannyl-2-pentenoate, (E)-2a.
