求翻译：was oleanolic acid methyl ester. Adding 2-iodoxybenzoic acid, oleanolic acid was oxidated to 12a, which was then converted to 12b–d via Corey–Bakshi–Shibata pyrrolidine catalystic reduction, Wolff-Kishner reduction, and Wittig reaction, respectively. Esterification and etherification of 1 at 3-position were relatively mo是什么意思？ 待解决

是果酸甲酯。加入2 - 碘酰基苯甲酸，齐墩果酸被氧化为12A，这是当时通过科巴克什，柴吡咯烷催化还原，沃尔夫kishner减少，Wittig反应，分别转换12B-D。比常见的反应，由于它周围的空间位阻的羟基发生酯化和醚1 3位相对更严格。 12E是乙基草酰氯酯化，然后水解得到12F。 12克-12I进行了相应的酸酐一夜之间甲苯中回流加入果酸。而12J可以轻松准备在室温下在DMF溶液与溴苄10I，与不同的羧基取代的苄溴化物应根据回流进行NAH通宵准备12K-12M的二恶烷醚化。终于，12J-12M，实现了从他们的甲基酯使用DMF溶液中回流崇礼。

是oleanolic酸甲酯。 添加2-iodoxybenzoic酸液,oleanolic酸被氧化且不为12a,然后它被转换成12b-d通过科里-巴克什的柴田先生pyrrolidine
