Novel Synthesis of Thioalkoxy-Substituted Oxa[9]helicenes by the Reaction of Helical Quinones with Thiols
摘要:
The reaction of helical quinone with thiols in the presence of acid such as HCl, para-toluene sulfonic acid (pTSA), or Yb(OTf)(3)center dot 3H(2)O to form resulted in the formation of thioalkoxy-substituted oxa[9]helicenes in moderate to good yields.
