Abstract

Chemistry Chemistry, Multidisciplinary Physical Sciences Science & Technology
Direct O-alkylation of tetrathiacalix[4]arene with 2-bromoacetamide afforded two conformational isomers (cone and 1,3-alternate) of tetrakis(carbamoylmethoxy)thiacalix[4]arene and 1,3-disubstituted bis(carbamoylmethoxy)thiacalix [4]arene, depending on the base used.
