” conformation (“1,3,5-up/2,4,6-down” conformation) to avoid otherwise increased steric repulsion between the vicinal substituents of the benzene frame. Use of such sterically bulky subunits within a molecule to enable it to adopt a thermodynamically favored conformation with mini-mum steric interactions has been dubbed as “steric gearing.”
”构象(“1,3,5-up/2,4,6-down”构象)以避免苯框架的邻位取代基之间的空间排斥增加。在分子中使用这种空间庞大的亚基,使其能够采用具有最小空间相互作用的热力学有利构象,被称为“空间传动”。
