Regioselective cyclopropanation of 2-phenylsulfonyl 1,3-dienes at either double bond was achieved by employing two different reagents. Sulfur ylide 1 resulted in a regiospecific cyclopropanation at the electron deficient double bond whereas an iron carbene, thermally generated from 5a, gave cyclopropanation exclusively at the electron rich double bond.

The viability of the 1,6-electrocyclic route to 1,3-cyclohexadienes has been significantly increased by using a phenylsulfonyl substituent in a multi-purpose (≥3) role.
1,6-电环化路线生成1,3-环己二烯的可行性已通过在多重(≥3)角色中使用苯磺酰基取代显著提高。
