Totalsynthesis of ceratopicanol (1) was achieved with a tandemcycloadditionreaction of allenyl diazo compound 6 via a trimethylenemethane (TMM) diyl intermediate. The TMM diyl mediated [2+3] cycloadditionreaction furnished the consecutive quaternary carbon centers and showed an unusual diastereoselectivity.
