Abstract
2-methyl-5(S)-hexanolide(1); the major component of pheromonal blend of the male carpenter bee was synthesized via Homer-Emmons reaction from Ethyl(S)-3-hydroxybutyrate(2a) which had been obtained by Baker's Yeast reduction in overall yield 39%.
Ethyl acetoacetate를 빵효모가 환원해 생산한 ethyl-(S)-3-hydroxy-butyrate(2a)를 키 랄 출발물질로 하여 수목에 피해를 끼치는 해충인 carpenter bee의 수컷이 분비하는 성 페로몬인 cis-2-methyl-5-hexanolide(1)을 diastereomer로 합성하였다. 역합성적 분석을 통한 합성계획으로부터 T-Goal로 Wittig반응을 잡고 출발물질을 환원하여 얻은 알데히드 4와 triethyl 2-phosphonopropionate(7)을 Horner-Emmons반응시켜
