First stereoselective concise synthesis of Neocosmosin A, with in vitro binding affinity for human opioid and cannabinoid receptors, has been reported using readily available starting materials such as methylacetoacetate, cyclohexanone, and homoallyl alcohol involved in the key transformations. There are three fragments involved in the synthesis of target molecule, bearing acid functionality, (R)-pent-4-en-2-ol
据报道,使用容易获得的起始原料,如乙酰乙酸甲酯,环己酮和均烯丙基醇,参与了关键的转化过程,首次合成了具有新的对人阿片和大麻素受体具有亲和力的新霉素A的立体选择性化合物。靶分子的合成涉及三个片段,分别带有酸官能团,(R)-戊-4-烯-2-醇和Weinreb酰胺,分别通过四个,八个和三个步骤合成。然后,将片段分四个步骤偶联,以总产率28.6%产生目标分子。
