Abstract
Substrate 1-[(phenylthio)methyl]-2-cycloalkenols 3a-d and 1-[2-alkyl-1,3-dithian-2-yl]cyclohexenols 1a-a were prepared by adding [(phenylthio)methyl]lithium and 2-lithio-2-alkyl-1,3-dithianes, respectively, in the 1,2-mode to various 2-cycloalkenones. The ranges of yields for the additions were 86-96% in the (phenylthio)methyl series and 69-88% in the dithiane series. A representative compound from each range of substrate tertiary allylic alcohols was then treated with a series of oxochromium(VI)-amine reagents such as pyridinium chlorochromate (PCC), pyridinium dichromate (PDC), the Collins reagent (CrO 3 .Pyr 2 ), and 2,2'-bipyridinium chlorochromate (BPCC)
