    Enynones in Organic Synthesis. 6. Synthesis of Spirocyclic Methylenecyclopentenones and Analogs of the Methylenomycin Class of Antibiotics. Mechanism of Phenol Catalysis
    摘要:
    Spirocyclic methylenecyclopentenones of general structure 18 were prepared in a single step from bis-acetylenic alcohols 29 by a process involving initial oxy-Cope rearrangement to afford (Z)-enynones 30-Z followed by electrocyclic ring closure. Mechanistic studies indicate that the initial step leading from 30-Z to 18 is a thermal 1,5-prototropic shift to afford dienols which can cyclize by a symmetry-allowed (pi(4)s + sigma(2)s + pi(2)a) process. This last step is catalyzed by certain phenols having low oxidation potentials, most likely by a mechanism involving single electron transfer. Dramatic rate enhancements were also observed for the cyclization of simple enynones 37 to methylenecyclopentenones 39 upon catalysis with either a-tocopherol (vitamin E, 40) or tert-butylcatechol(41). Further enhancements in both rate and yield were obtained under conditions of photoassisted single electron transfer (PET), which afforded 39 in yields of 80-98%.

  • Photooxygenation of 3,3-dialkylsubstituted allyl alcohols. Occurrence of syn preference in the ene addition of1O2 atE/Z-isomeric allyl alcohols

    oxygenation products formed. The rate and selectivity of the 1O2 additions were found to be markedly dependent on the degree of substitution (i.e. H-availability) at the allyl position which is Z-orientated to the carbinol group. The allyl alcohols with a Z-3-methyl group, 1 and the E-isomers of 7 to 10, showed practically the same reactivity towards 1O2 and formed only the two oxygenation products of type
