It is also possible to access the aryl SPG from the thiol via alkylation and subsequent oxidation with sodium tungstate (Figure ). PMB-R and oNB-R can all be made via this route in high yield. SES and SMOPS are made via the addition of the thiol to the vinyl trimethylsilane and methyl acrylate with AIBN, respectively (See Supporting Information). TBS-R and Rongacyl cannot be accessed via this method due to the inability to obtain the corresponding alkyl halide. To access alkyl SPGs, benzyl bromide was reacted with the corresponding sulfinate in high yield (Figure ).
