  Regio- and stereoselective cyclopropanation of functionalised dienes. Novel methodology for the synthesis of vinyl- and divinyl-cyclopropanes

  摘要：

  Dienes, bearing an electron-withdrawing substituent at C-1, are cyclopropanated regio- and stereo selectively at the C-C double bond proximal to this electron-withdrawing group. The highest selectivity is observed in the case of dienylboronates. The cyclopropanation of these substrates affords almost exclusively the synthetically useful 1-boronato-2-vinyl-cyclopropanes.

• Synthesis of <i>Z</i>-(Pinacolato)allylboron and <i>Z</i>-(Pinacolato)alkenylboron Compounds through Stereoselective Catalytic Cross-Metathesis

  first examples of catalytic cross-metathesis (CM) reactions that furnish Z-(pinacolato)allylboron and Z-(pinacolato)alkenylboron compounds are disclosed. Products are generated with high Z selectivity by the use of a W-based monoaryloxide pyrrolide (MAP) complex (up to 91% yield and >98:2 Z:E). The more sterically demanding Z-alkenylboron species are obtained in the presence of Mo-based MAP complexes

  A concise synthesis of monobenzofused 1,4-azaborine phosphine ligands (Senphos) is described. These Senphos ligands uniquely support Pd-catalyzed trans-selective hydroboration of terminal and internal 1,3-enynes to furnish corresponding dienylboronates in high efficiency and diastereoselectivity. X-ray structural analysis of the Senphos-Pd(0) complex reveals a κ2-P-η2-BC coordination mode, and this

• Remarkable Stereocontrol in the Palladium-Catalysed Cyclopropanation of Vinyl- and Dienylboronates by Substituted Diazoalkanes

  DOI：10.1002/1615-4169(200212)344:10<1063::aid-adsc1063>3.0.co;2-l

  日期：2002.12

  Substituted diazoalkanes react smoothly, in the presence of catalytic amounts of Pd(OAc)(2), with a range of vinyl- and dienylboronates, affording in good to excellent yields, the corresponding trisubstituted cyclopropanes. The reaction is remarkably regio-, chemo-, and diastereoselective. The synthetic utility of this novel protocol is illustrated by the efficient assembly of the middle fragment of ambruticin.
