Sulfones Q 0600 Diversity-Oriented Synthesis of Functionalized Diaryl Sulfones by Regioselective [3 + 3] Cyclizations of 1,3-Bis(siloxy)buta-1,3-dienes with 2-(Arylsulfonyl)-3-ethoxy-2-en-1-ones: Scope andLimitations. -The formal [3 + 3] cycloaddition of readily prepared 2-(arylsulfonyl)-3-ethoxy-2-en-1-ones with bis(siloxy)buta-1,3-dienes allows the synthesis of a variety of functionalized diarylsulfones (35 examples). -(SHKOOR, M.; RIAHI, A.; FATUNSIN, O.; REINKE, H.; FISCHER, C.; LANGER*, P.; Synthesis 2009, 13, 2223-2235; Inst.
