合成了轴端带有肉桂酸酯基团的轮烷。在钯催化剂的存在下，通过Tsuji-Trost烯丙基化反应，以极高的产率用笨重的丙二酸酯修饰了末端封端。
Rotaxanes possessing a cinnamyl ester group at the axle terminal were prepared. The terminal end-cap was modified with a bulky malonate ester in excellent yield by the Tsuji-Trost allylation reaction, which was carried out in the presence of a palladium catalyst.
