Cyclizations and cycloadditions of acetylenic sulfones on solid supports
Back, Thomas G.,Zhai, Huimin
, p. 326 - 328 (2006)
Acetylenic sulfones attached to solid supports by means of ester linkers were employed in a variety of cyclization and cycloaddition reactions, followed by cleavage of the products from the resin by ester hydrolysis or reductive desulfonylation. The Royal
