  An efficient synthesis of pterosin C and other pterosins

  摘要：

  已经开发出了一种通用的合成途径来制备蕨类植物中存在的对位香豆素类化合物——翅果酸，具体来说就是欧洲蕨（Pteridium aquilinum）。该合成途径的示例是通过使用甲基丙烯酸氯对2-(2,6-二甲基苯基)乙醇的甲基醚进行弗里德尔-克拉夫茨双取代反应来合成(2S,3S)-翅果酸C。将得到的1,3-茚二酮脱甲基，并在乙酸和乙酸钠的存在下用锌和乙酸还原，得到了翅果酸C二醋酸酯的消旋顺式和反式异构体的混合物，该混合物经水解得到了相应的翅果酸。通过S-(+)-α-苯基丁酸酯的分离和解析，得到了(2S,3S)-翅果酸C和(2R,3R)-翅果酸C。其他翅果酸则是从1,3-茚二酮以消旋混合物的形式制备的。

• Generation and Cycloaddition Behavior of Spirocyclic Carbonyl Ylides. Application to the Synthesis of the Pterosin Family of Sesquiterpenes

  The Rh(II)-catalyzed reaction of 1-acetyl-1-(diazoacetyl)cyclopropane and ethyl 3-(1-acetyl-cyclopropyl)-2-diazo-3-oxopropiolate with various dipolarophiles afforded dipolar cycloadducts in good yield. The reaction involves the formation of a rhodium carbenoid and subsequent transannular cyclization of the electrophilic carbon onto the adjacent keto group to generate a five-membered cyclic carbonyl ylide which undergoes a subsequent dipolar cycloaddition reaction. The regiochemical results encountered can be rationalized on the basis of FMO considerations. For carbonyl ylides, the HOMO dipole is dominant for reactions with electron deficient dipolarophiles, while the LUMO becomes important for cycloaddition to more electron rich species. A short synthesis of several members of the pterosin family of sesquiterpenes is described in which the key step involves a dipolar cycloaddition using a carbonyl ylide. The Rh(II)-catalyzed reaction of 1-acetyl-1-(diazoacetyl)-cyclopropane with cyclopentenone afforded a dipolar cycloadduct in good yield as a 4:1 mixture of diastereomers. Treatment of the major cycloadduct with triphenylphosphonium bromide in the presence of sodium hydride gave the expected Wittig product. The reaction of this compound with acid in the presence of various solvents gave rise to several members of the pterosin family. The overall sequence of reactions can best be described as proceeding by an initial oxy-bridge ring opening followed by dehydration and a subsequent acid-catalyzed cyclopropyl ring opening. The facility of the process is undoubtedly related to the aromaticity gained in the final step.
