Notizen:
The cigarette beetle pheromone (-)-serricorole (1) has been synthesized in 23% overall yield by an eight-step sequence starting from N-propionylsultam 3. The synthesis features asymmetric anti- and syn-aldolizations 3 → 4 and 8 → 9, a non-destructive N-acylsultam cleavage with lithiated ethylphenylsulfone (10 → 12), and the smooth, Ti-mediated cyclization of β-acyloxy-ketone 2 to dihydropyranone 14.
