| titleOfInvention | Synthesis of cyclic disulfone compounds |
| abstract | This invention relates to a method of synthesizing bis-sulfones of the formula <IMAGE> wherein R1 and R2 each are hydrogen, alkyl, phenalkyl, phenyl or phenyl-substituted with an electron-donating or electron-withdrawing group and n is an integer 2, 3 or 4 (a) by reacting a 1,3-dithio compound with n-butyllithium to generate the anion of said compound, (b) reacting said anion with a carbonyl compound to give the 2-substituted carbonol anion intermediate, (c) reacting said intermediate with an acyl chloride or a chloroformate to give the corresponding ester, and (d) reacting said ester with a peracid to give the bis-sulfone product. The subject invention also is concerned with the novel intermediates of step (c). |
