Stereospecific C-S bond formation from chiral tertiary alcohols by quinone-mediated oxidation-reduction condensation using alkyl diphenylphosphinites and its application to the synthesis of a chiral tertiary thiol
Oxidation-reduction condensation between 2-sulfanyl-1,3-benzothiazole (Btz-SH) and the alkyl diphenylphosphinites 1, prepared from tertiary alcohols, proceeded smoothly in the presence of 2,6-di-t-butyl-1,4-benzoquinone (DBBQ) and the corresponding S-alky
