Economical and environmentally friendly syntheses of 2-(phenylsulfonyl)-1,3-cyclohexadiene and 2-(phenylsulfonyl)-1,3-cycloheptadiene.
A large-scale and inexpensive synthesis of dienes 1 and 2 has been developed via a four-step procedure starting with benzenethiol and the corresponding cyclic ketone. No chromatography is required.
