    Synthesis of the bicyclo[3.2.0] ring systems from 4-allylcyclobutenones. Intramolecular ketene/alkene cycloadditions
    摘要:
    A general synthesis of bicyclo[3.2.0]heptenones from 4-allylcyclobutenones is described. The rearrangement is envisaged to involve an electrocyclic ring opening of the cyclobutenone and subsequent intramolecular 2 + 2 cycloaddition of the resulting vinylketene to the nonconjugated allylic alkene moiety. This method is particularly suitable for the synthesis of highly substituted derivatives since the regiochemistry of the substitution pattern is conveniently controlled. The scope of the rearrangement and the mechanism are discussed.

Two ring-closing metathesis reactions were then used to form the 13- and 8-membered rings leading to Z-72 and 74, the latter of which was quickly elaborated into ircinal A (5) via ircinol A (75). The synthetic 5 thus obtained was converted into manzamine A (1) following literature precedent. This concise synthesis of ircinal A required a total of 24 operations from commercially

    stereoselective synthesis of a tricyclic model compound of taxane diterpenes was achieved. The eight-membered B ring was constructed on the basis of a [6+2] cycloaddition reaction of a dicobalt acetylene complex with an enol silyl ether of cyclohexanone. After conversion of the cobalt complex moiety to an epoxide and introduction of a 3-cyanopropyl group, the A ring was formed via an intramolecular cyclization
