  • Chiral α-substituted allylboronates in a one-pot three-component asymmetric allylic alkylation/carbonyl allylation reaction sequence — Applications to the syntheses of (+)-(3<i>R</i>,5<i>R</i>)-3-hydroxy-5-decanolide and (–)-massoialactone
    作者:Lisa Carosi、Dennis G. Hall

    The use of different organomagnesium reagents in the copper-catalyzed allylic alkylation of 3-chloropropenyl boronates with chiral phosphoramidite ligands produces the desired α-substituted allylic boronate reagents in high regioselectivity and with modest to high enantioselectivities (up to 96% ee). The size of the incoming alkyl substituent from the organomagnesium reagent was found to impact the yield and selectivity of the allylic alkylation. A one-pot procedure for the preparation of these chiral allylic boronates followed by a Lewis acid (BF3) catalyzed addition to aldehydes delivers the desired allylboration products, homoallylic secondary alcohols, in good yields and very high diastereoselectivity. This three-component reaction methodology was applied to the syntheses of two lactone-containing natural products, (–)-massoialactone and (+)-(3R,5R)-3-hydroxy-5-decanolide. The key step of these syntheses involved the one-pot enantioselective copper-catalyzed allylic alkylation/allylboration reaction with a benzylic aldehyde, and afforded the desired product in 87% yield, 92% ee, and high E/Z selectivity in a ratio of 22:1. Remarkably, the allylic alkylation step of this sequential reaction was performed with a low catalyst loading of 2 mol% on a scale of >15 mmol that can provide multiple grams of the three-component product.

    在铜催化的 3-氯丙烯基硼酸酯与手性磷酰胺配体的烯丙基烷基化反应中,使用不同的有机镁试剂可产生所需的α-取代烯丙基硼酸酯试剂,且具有很高的区域选择性和适度到很高的对映选择性(高达 96% ee)。研究发现,来自有机镁试剂的烷基取代基的大小会影响烯丙基烷基化的产率和选择性。采用一锅法制备这些手性烯丙基硼酸酯,然后在路易斯酸 (BF3) 催化下与醛加成,就能得到所需的烯丙基硼化产物--均烯丙基仲醇,而且产率高,非对映选择性也非常高。这种三组份反应方法被应用于合成两种含内酯的天然产物,即 (-)-massoialactone 和 (+)-(3R,5R)-3-hydroxy-5-decanolide 。这些合成的关键步骤是铜催化的烯丙基烷基化/烯丙基硼化反应与苄基醛的一锅对映选择反应,以 87% 的收率、92% 的ee 和 22:1 的高 E/Z 选择性得到了所需产物。值得注意的是,这个连续反应的烯丙基烷基化步骤是在 2 摩尔%的低催化剂负载下进行的,催化剂的用量为 15 毫摩尔,可以提供多克三组分产物。
  • First total synthesis of verbalactone, a macrocyclic dilactone isolated from Verbascum undulatum
    作者:Siddhartha Gogoi、Nabin C. Barua、Biswajit Kalita

    日期:2004.7
    Verbalactone, a new macrocyclic dilactone was synthesized efficiently in a steroselective manner involving a Barbier–Grignard reaction, a Sharpless asymmetric dihydroxylation, monotosylation, epoxidation, ring opening of the epoxide, hydrolysis and lactonization. A δ-lactone, (+)-(3R,5R)-3-hydroxy-5-decanolide was also formed along with the dimeric lactone.

    Novel antimicroalgal substances halymecins A (1), B (2) and C (3) were isolated from the fermentation broth of a Fusarium sp. and halymecins D (4) and E (5) from an Acremonium sp. The structures of these halymecins, Fig. 1, were determined based on extensive 2D NMR studies as well as mass spectral data. These chemical structures are conjugates of di- and trihydroxydecanoic acid. Halymecin A showed antimicroalgal activity against Skeletonema costatum.
