  Controlling π-Facial Diastereoselectivity in the 1,3-Dipolar Cycloadditions of Diazomethane to Chiral Pentenoates and Furanones:  Enantioselective Stereodivergent Syntheses of Cyclopropane Hydroxy Acids and Didehydro Amino Acids

  摘要：

  The title compounds have been synthesized in both enantiomeric forms and in good overall yields by using D-glyceraldehyde as the single chiral precursor. The efficiency and usefulness of the synthetic routes have been secured by performing controlled manipulations of the functional groups and by highly stereoselective transformations, namely Wittig-Horner condensations and cyclopropanations. Cyclopropane derivatives have been synthesized through 1,3-dipolar cycloaddition of diazomethane to chiral pentenoates or furanones obtained, in turn, from D-glyceraldehyde. Syn/anti stereochemistry of the cycloadducts has been unequivocally assigned and rationalized. Since pi-facial diastereoselectivity involved in these cycloadditions is the opposite for cyclic and open-chain structures, enantiomeric series of products can be derived.

  comparable. Additions catalyzed by 1 are strongly sensitive to steric effects. Highly substituted olefins afford cyclopropanes in only poor yield. The preferential cis-selectivity observed in reactions catalyzed by 1 is attributed to dominant interactions between the ligand of the catalyst and the substituents of both olefin and diazoacetate, which overrule the steric interactions between olefin and diazoacetate

  用[Rh 2 （4 S）-phox} 4 ]（1 ; phox =四[[4 S）-四氢-4-苯基恶唑-2-酮]）研究了Rh 11催化的重氮乙酸类酯类化合物向烯烃的加成反应。，[Rh 2 （（2 S）-mepy} 4 ]（2 ; mepy =四[甲基（2 S）-四氢-5-氧杂吡咯-2-羧酸酯]）和[Rh 2（OAc）4 ]（3）。当用2和3催化时，优先提供反式-环丙烷羧酸酯，顺式-异构体是1的主要产品。通常，用1和2获得的对映选择性是可比较的。1催化的加成对位阻效应非常敏感。高度取代的烯烃仅以较差的收率提供环丙烷。在1催化的反应中观察到的优先顺式选择性归因于催化剂的配体与烯烃和重氮乙酸酯的取代基之间的显性相互作用，该相互作用抵消了烯烃和重氮乙酸酯在过渡态下的卡宾转移的空间相互作用。

  A new efficient catalytic system consisting of Cu(OAc)2, 2,4-lutidine, and ZnCl2 was found for the cyclopropanation of unsaturated compounds with methyl diazoacetate. In the case of conjugated dienes, the process occurs regioselectively at the most alkylated C=C bond.
