Rhodium(I)-catalyzed cyclization of allenyl aldehydes with various alkynes was investigated. The cyclizations of internal alkynes that have both an electron-rich aromatic ring and an electron-withdrawing group at the terminus afforded [2+2+2] cycloaddition products in good yields with good to high regio- and enantioselectivity, while the reactions of terminal alkynes gave dienyl ketones instead of [2+2+2] cycloaddition products in good yields. These results indicate that the nature of the alkynes greatly influences the reaction course.
