Synthesis and Characterization of Thiacalix[4]monocrowns Modified by Thioether Groups on the Lower Rim
摘要:
A series of thiacalix[4]monocrowns in 1,3-alternate conformation containing thioalkyl fragments was synthesized by the reaction of corresponding distal thiacalix[4]arene derivatives with oligoethylene glycols using a Mitsunobu protocol.
