has been developed. These species were employed as haptens to elicit catalytic antibodies capable of controlling the corresponding bicyclic hydrocarbon formation from linear quasi-triisoprenoid substrates. Temperature dependent NMR studies of cis-fused compounds proved the existence of two conformational states. Hapten 20b has elicited an antibody that efficiently catalyses a tandem cationic cyclisation
已经开发了一种有效的合成途径,可以合成顺式和反式外消旋4 a,6-二甲基八氢
喹啉-N-氧化物。这些物种被用作半抗原,以引发能够控制线性准三
异戊二烯酸底物形成相应双
环烃的催化
抗体。取决于温度的NMR研究表明,顺式融合的化合物存在两种构象态。Hapten 20b引发了一种
抗体,该
抗体可有效催化串联阳离子环化反应,从而导致桥甲基化十氢化
萘。
