  A convenient two-step procedure for the construction of sulfur-containing quaternary centers from tert-alcohols involving chiral ones is established. tert-Alkyl diphenylphosphinites 1 were easily prepared in excellent yields from tert-alcohols and ClPPh2 by the combined use of Et3N and a catalytic amount of DMAP. Subsequent condensation of 1 with thiol 3 smoothly proceeded in the presence of quinone 2d to afford the corresponding tert-alkyl sulfides 4 in good to high yields via SN2 displacement. Removal of benzothiazol-2-yl group of (R)-4j was achieved with LiAlH4 to afford the desired chiral thiol (R)-5 in high yield.

  建立了一种从涉及手性叔醇的叔醇出发，构建含硫季碳中心的方便两步法。叔烷基二苯膦亚基1可通过叔醇与ClPPh2在Et3N和催化量DMAP的共同作用下，轻松制备并获得极佳产率。随后，在醌2d的存在下，1与硫醇3的缩合反应顺利进行，通过SN2取代反应以良好至高产率得到相应的叔烷基硫醚4。使用LiAlH4去除(R)-4j的苯并噻唑-2-基团，以高产率得到了所需的手性硫醇(R)-5。
