求翻译:Methoxy groups atC-3 of iso-seco-tanapartholides were distant from the a-methylene-g-lactone and, hence, could not sterically hinder its approach toward nucleophiles. Moreover, iso-seco-tanapartholides bear open ring structures enabling conformational rotations that can minimize steric hindrance是什么意思? 待解决

isoseco tanapartholides甲氧基小组atC3从次甲基g内酯是遥远的,并且,因此,不能sterically妨害它的方法往nucleophiles。而且, isoseco tanapartholides负担开放圆环结构使能可能使位的妨碍减到最小的构象的自转

甲氧基组 atC 3 的 iso-seco-tanapartholides 是遥远的从一-亚甲基-g-内酯和,因此,空间不能阻碍其态度亲核试剂。此外,iso-seco-tanapartholides 熊开放环结构使构象的循环,可以最小化空间位阻

甲氧组ATC3ISO的一行的有很大的距离tanapartholides的A-甲基-G-lactone和,因此,无法sterically阻碍其nucleophiles。 此外,国际标准化组织的一行-tanapartholides承担开放环结构使conformational旋转,可以最大限度地减少steric障碍
