  摘要：

  功能化的烯丙基卤化物，作为制备取代有机金属试剂的有用起始材料，可以通过一种直接的方法简单地获得。Hoveyda的钌卡宾催化剂3，以催化量（2 mol%）使用，能够促进烯丙基溴和氯与多种不同取代烯烃的交叉复分解反应，以令人满意的产率得到相应的功能化烯丙基卤化物。使用烯丙基氯作为复分解反应伙伴时，主要得到trans-烯烃的非对映异构体，比例达到90:10（trans:cis）。这一反应为制备功能化有机金属试剂的有价值前体提供了一种简单且易行的方法。特别是，展示了功能化烯丙基溴（10b和13）在[Cr(Salen)Cl]促进的手性选择性野崎-日山反应中的应用。

• Synthesis of Petrosins C and D

  Petrosins C and D (5 and 6), diastereomers of the known natural products petrosin (1), petrosin A (2), and petrosin B (3), have been prepared. The synthetic route involved initial creation of a 16-membered bis-pyridine intermediate, exemplified by compounds 7, 28, and 52. Several different methods for formation of the macrocycle were evaluated, and the most efficient (Schemes 7-9) involved use of Z double bonds in the six-carbon chains linking the two pyridine rings. This approach permitted the two pyridine subunits (37 and 39) to be joined by alkylation of a lithiated alpha-methylpyridine with an allylic chloride (e.g., 37 + 39 --> 40 and 49 --> 45). Bisannulation of compounds 7 and 28 was complicated by a surprising lack of acidity of the a-pyridyl methylene groups. Eventually, this problem was solved by stepwise introduction of two allyl groups, using the more acidic sulfone for introduction of the first (e.g., 52 --> 53) and direct allylation to introduce the second (e.g., 54 --> 55 + 56). The bisannulation was completed by hydroboration and conversion of the primary alcohols into methanesulfonate derivatives, which cyclized to afford bis-pyridinium derivatives. Reduction of these intermediate salts with sodium borohydride provided crystalline bis-enol ethers (60 and 63) and the relative configuration was established by single-crystal X-ray analysis of 63. After hydrolysis of the enol ethers to the corresponding ketones, the syntheses of 5 and 6 were completed by enolate methylation. As expected, compounds 5 and 6 do not form imine derivatives when treated with primary amines, presumably because of A(1,3) strain.

  imidazolium salts, γ-substituted allyl chlorides reacted with alkyl Grignard reagents to undergo substitution reactions in an SN2′-selective fashion, where the magnesium ate complexes [(N-heterocyclic carbene-MgR3)−(MgX)+] of imidazol-2-ylidenes or imidazol-4-ylidenes, generated in situ, were postulated as the active species. It was observed that the reactions with imidazol-4-ylidene catalysts were faster

  Functionalised allyl halides, useful starting materials for the preparation of substituted organometallic reagents can be simply obtained by a straightforward approach. Hoveyda’s ruthenium carbene catalyst 3, used in catalytic amount (2 mol%), is able to promote the cross metathesis of allyl bromide and chloride with a variety of different substituted olefins giving the corresponding functionalised allyl halides in satisfactory yields. trans-Olefins are obtained as major diastereoisomers reaching 90:10 (trans:cis) ratio when allyl chloride is used as the metathesis partner. This reaction represents a simple and accessible way for the preparation of valuable precursors for functionalised organometallic reagents. In particular, the use of functionalised allyl bromides (10b and 13) in the enantioselective Nozaki-Hiyama reaction promoted by [Cr(Salen)Cl] is presented.
