摘要：

The synthesis, structure and ring-closing metathesis (RCM) reactions of polyether bridged biscalix[4]arenes 6 in the partial cone conformation with upper rim allyl substituents are reported. The RCM reaction modes depend on the length of polyether chain. Diethylene glycolic chain produced the dimer 7a and linear oligomer 7a' with multi-cavities, whereas triethylene and tetraethylene glycolic chains allowed direct cyclization through intramolecular head-to-tail pattern to yield novel bridged biscalix[4]arenes 7b-c.
