Regioselective molybdenum-catalyzed hydrostannations of acetylenic ketones give rise to allenoxystannanes, which can be subjected to subsequent aldol reactions. Because aldehydes are not affected under the reaction conditions used, the hydrostannation-aldol addition can be performed as a one-pot reaction, providing easy access to substituted Morita-Baylis-Hillman-type products in a highly stereoselective fashion.
