[摘要]:Microwave irradiations allow the preparation of unsaturated bambusurils in 85% yield compared to 20% yield under classical reaction conditions. Five new bambusurils were synthesized including unsaturated derivatives Allyl(8)BU[4] and Allyl(12)BU[6] bearing diallylglycoluril units. The reactivity of Allyl(8)BU[4] was tested in a variety of organic reactions showing that this macrocycle acts as a classical double bond-bearing product. The first monofunctionalized bambusuril Allyl(7)HepBU[4] prepared by a cross metathesis reaction is also reported. |
