✦ Synopsis

Michael reaction of macrocyclic ketene silyl acetals or a-enones occurs smoothly under electron transfer conditions while the reaction of 6-membored analogs is more sluggish, indicating the importance of the ring flexibility to allow the a,~-carbon-carbon bonds of both reaction components to rotate when the radical species are generated.
