What is Intramolecular rearrangement of 1,3-bistriflate ester of thiacalix[4]arene to 1,2-counterpart: an efficient di-O-protection method for the stereoselective synthesis of anti-1,2-diethers about?
A net anti-selective dialkylation of the proximal hydroxy groups of thiacalix[4]arene 2 is achieved for the first time via the initial protection of the two proximal hydroxy groups of compound 2 with Tf moieties by intramolecular rearrangement of easily preparable 1,3-bistriflate ester 3 to 1,2-counterpart 4, followed by anti-selective dialkylation of the remaining hydroxy groups with alkyl halides or under the Mitsunobu conditions and subsequent removal of the Tf moieties.
