Me(3)Al and Cp(2)ZrCl(2) give rise to an especially effective reagent mix that results in virtually complete control of regiochemistry upon carboalumination of 1-alkynes. One timely application to coenzymeQ10 is highlighted. Regioisomers from subsequent coupling, which would otherwise be very difficult to separate, are avoided.
