The total synthesis of Kopsia lapidilecta alkaloid (±)-lapidilectine B is described. Notable elements of this synthesis include the first natural products application of the Smalley azido−enolate cyclization to form the 1,2-dihydro-3H-indol-3-one (indoxyl) core and installation of the pyrrolidine ring by a 2-azaallyllithium [3+2] cycloaddition with the acetylene equivalent phenyl vinyl sulfide.
