title: Total synthesis of antofine using the net [5+5]-cycloaddition of gamma,delta-unsaturated carbene complexes and 2-alkynylphenyl ketones as a key step.
abstract: A compound containing all of the carbons of the anticancer agent antofine was produced in a single step from the coupling of a gamma,delta-unsaturated carbene complex with a 2-alkynylphenyl ketone derivative. Subsequent conversion to antofine was effected in three steps.
