The structure and absolute stereochemistry of fauronyl acetate and cryptofauronol have been elucidated as formulae I and II, respectively, by the following series of reactions coupled with spectral determinations. Fauronyl acetate (I) and cryptofauronol (II) were interconverted by hydrolysis and acetylation. Fauronyl acetate was transformed to the ketone (VIII), in which the environment of the carbonyl group was established, and to valeranone whose absolute stereostructure (XIV) is known.
通过以下一系列反应并结合光谱测定,乙酸苯甲醛酯和隐苯甲醛醇的结构和绝对立体化学已分别阐明为式I和II。 Fauronyl Acetate (I) 和 Cryptofauronol (II) 通过水解和乙酰化相互转化。乙酸呋喃酯转化为酮 (VIII),其中建立了羰基环境,并转化为绝对立体结构 (XIV) 已知的戊酮。
