  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.

  Olefin cross-metathesis was used for the efficient incorporation of an E-olefin between two cyclopropane residues. The generation of a bis-cyclopropyl alkene homodimer, followed by cross metathesis with a terminal vinyl polycyclopropane, provided excellent yields of the targeted compounds with good olefin stereoselectivity. The strategy was applied to generation of a quinta-cyclopropane intermediate
