position of the conformationalequilibria in a series of 2-substituted cyclohexanone ketals have been determined by 1H NMR. For the ethylene ketals 6 the equatorial conformer has been found to be enthalpically preferred. The other ketal system (5, 7–9), in contrast, display predominance of axial conformers. The reasons for this behavior are discussed in terms of rotameric conformations of acetal chains
在一系列2-取代的环己酮缩酮中,构象平衡的位置已经通过1 H NMR确定。对于乙烯缩酮6,发现赤道构象异构体在焓上是优选的。相比之下,其他缩酮系统(5、7–9)则显示出轴向整合子的优势。根据乙缩醛链的旋转异构构象讨论了这种行为的原因。

Lilac aldehydes are considered as principal olfactory molecules of lilac flowers. We have designed, prepared, and evaluated a set of racemic seco-analogues of such natural products. The synthesis employs commercially available α-chloroketones as substrates that are transformed in four steps to target compounds. Their qualitativeolfactory analysis revealed that the opening of the tetrahydrofuran ring
