Direct Cross-Couplings of Propargylic Diols

[Pd(PPh3)4] catalyzes a Suzuki–Miyaura-like twofold cross-coupling sequence between underivatized propargylic diols and either aryl or alkenyl boronic acids to furnish highly substituted 1,3-dienes. Thus, 2,3-diaryl-1,3-butadienes and their dialkenic congeners ([4]dendralenes) are delivered in a (pseudo)halogen-free, single-step synthesis which supersedes existing methods. Allenols are also readily formed. Treatment of these single- and twofold cross-coupled products with acid leads to remarkably short syntheses of highly-substituted benzofulvenes and aryl indenes, respectively.

Oxidation of 2,2,3,3-tetramethyl-1,4-diphenyl-5,6-dithiabicyclohexane with m-chloroperbenzoic acid gives two isomeric endo- (4a) and exo-sulfoxides (4b), three S,S'-dioxides (endo, exo-5a, exo, exo-5b, and endo, endo-5c), and an S,S,S'-tioxide (6).
