Uncommon Regioselectivity in Thiacalix[4]arene Formylation
To reveal the alternative ways for upper-rim thiacalixarene derivatization, the formylation reactions (Gross and/or Duff conditions) of the corresponding tetrapropoxythiacalix[4]arene immobilized in the 1,3-alternate conformation were system...

Uncommon Regioselectivity in the Thiacalix[4]arene Series: Gross Formylation of the Cone Conformer
Thiacalix[4]arene immobilized in the cone conformation undergoes a direct Gross formylation reaction (Cl2CH-O-CH3/SnCl4/CH2Cl2) to give the upper-rim formylated thiacalixarene. Albeit using excess of the formylation agent a...
