backbone and the allyl side chains, Lewis acid-catalyzed three-component condensation reactions of carbonyl compounds, N-trimethylsilylcarbamates, and allyltrimethylsilane are studied. The reaction of these three compounds took place in the presence of a catalytic amount of TrClO4 at 0°C to yield the corresponding N-homoallylcarbamates in good yields. This reaction was also applied to the synthesis of a
为了同时构建聚氨酯主链和烯丙基侧链,研究了路易斯酸催化的羰基化合物,N-三甲基甲硅烷基氨基甲酸酯和烯丙基三甲基硅烷的三组分缩合反应。这三种化合物的反应在催化量的TrClO 4的存在下于0℃进行,以高收率得到相应的N-均烯丙基氨基甲酸酯。该反应还用于合成具有烯丙基侧链的聚氨酯。
