We present the absolute configuration (AC) determination of an alkane, trans-perhydroazulene (1), that displays the naturally very common trans fused [5,7] ring system. We outline the first synthesis yielding enantiopure 1 and the application of optical rotatory dispersion (ORD) and vibrational circular dichroism (VCD) techniques. The spectroscopic results are in excellent agreement with the computed
我们提出了一种烷烃,反式过氢腈(1)的绝对构型(AC)测定,该化合物显示出非常自然的反式稠合[5,7]环系。我们概述了产生对映体1的第一个合成方法,以及旋光色散(ORD)和振动圆二色性(VCD)技术的应用。光谱结果与B3LYP / 6-311 ++ G(2d,2p)上的ORD和B3LYP / 6-311 ++ G(d,p)上的VCD光谱非常吻合。 AC为(R,R)-(+)-1。
