Conformation Induction Between Neighboring Dimethylpentane Segments
摘要:
A 2,4-dimethylpentane unit can be rendered monoconformational by the presence of a conformation-inducing group (an inductor group) at C-1 (cf. 6). The resulting entity may serve as an inductor group to control in turn the conformation of a neighboring dimethylpentane segment (cf. 7). This holds if the inducing dimethylpentane segment is isotactic (cf. 15, 25), but not when it is syndiotactic (cf. 28).
