reaction of labdane-type diterpene (−)-(5S,9S,10S,13S)-labd-7-en-15-oic acid and (+)-(5S,8R,9R,10S,13R)-8-hydroxylabdan-15-oic acid, isolated from aerial parts of Ageratina jocotepecana is presented. In the presence of dibenzylazodicarboxylate and proline followed by an in situ reduction, the corresponding hydrazino alcohols were obtained. It is demonstrated that the first diterpene moiety had no influence
摘要 拉丹型二萜 (-)-(5 S ,9 S ,10 S ,13 S )-labd-7-en-15-oic 酸和 (+)-(5 S ,8 )的第一次亲电 α-胺化反应介绍了从Ageratina jocotepecana地上部分中分离得到的R ,9 R ,10 S ,13 R )-8-hydroxylabdan-15-oic acid 。在偶氮二甲酸二苄酯和脯氨酸存在下,然后是原位还原,得到相应的肼基醇。结果表明,第一二萜部分对随后由所用催化剂控制的非对映选择性没有影响,与主要控制产物的非对映化学的第二二萜相反。
