    甲基酮作为卤代烷替代物:一种用于战略性官能团转化的脱酰卤化方法
    摘要:
    卤代烷是获得多种官能团 (FG) 的通用前体。由于其不稳定性,卤代烷替代物的开发对于复杂分子的合成具有重要的战略意义。鉴于常见烷基酮固有的稳定性和易于衍生化的特点,我们在此报告了一种脱酰卤化方法,可将各种甲基酮转化为相应的烷基氯、溴化物和碘化物。该反应是通过形成芳香族副产物(即 1,2,4-三唑)来驱动的,其中使用N'-甲基吡啶甲酰肼酰胺 (MPHA) 形成前芳香族中间体,并使用卤素原子转移 (XAT) 试剂来猝灭反应。烷基中间体。该反应可有效地从多种甲基酮中生成伯烷基卤和仲烷基卤,并具有广泛的 FG 耐受性。它还适用于复杂的天然产物衍生和含氟基材。此外,还实现了甲基酮一锅法转化为各种其他FG,以及通过脱酰卤化与烯烃和炔烃成环。此外,还证明了烷基碘的不寻常的迭代同系化。最后,机理研究揭示了脱酰碘化反应的一个有趣的双 XAT 过程,这可能具有超出本工作范围的影响。

  • Structure and reactions of oxametallacyclobutanes and oxametallacyclobutenes of ruthenium
    作者:John F. Hartwig、Robert G. Bergman、Richard A. Andersen
    DOI:10.1021/om00055a061
    日期:1991.9
    Structure and reactivity studies are reported with the ruthenium metallacycles prepared as described in the previous paper. A C-C cleavage reaction by an apparent beta-Me elimination pathway at 45-degrees-C is reported for the PMe3-substituted oxametallacyclobutane complex (PMe3)4Ru(OC(Me)(Ph)CH2) (1), while the analogous DMPE-substituted metallacyclobutane (DMPE)2Ru(OC(Me)(Ph)CH2) (2) is stable at 140-degrees-C. Similarly, compound 1 undergoes insertion of CO into the metal-carbon bond, while 2 is inert toward this substrate. Addition of protic acids and electrophiles leads to rapid extrusion of alpha-methylstyrene with both metallacycles. X-ray structural analysis of the acetone dianion complex (PMe3)4Ru((CH2)2CO) (17) was performed and displays a dihedral angle of 46-degrees-C in the metallacycle. In contrast, the 4,4-dimethyl-2-butanone dianion complex (PMe3)4Ru(CH2C(CHCMe3)O) (15) contains a flat metallacycle that is bound through the CH2 group and the oxygen atom. Reactivity studies with 15 showed that, unlike compounds 1 and 2, the organic portion remained intact upon addition of protic acids. The addition of 4,4-dimethyl-2-butanone led to a second C-C cleavage reaction, forming the di-tert-butylacetylacetonate complex (PMe3)3Ru(Me)(CH(COCH2CMe3)2) (19). Reactivity studies with 17 showed reversible formation of the isolable oxatrimethylenemethane complex 18, which was isolated and structurally characterized. Addition of acetone to 17 led to formation of mesityl oxide dianion complex (PMe3)4Ru(OC(Me)CHC(Me)CH) (19); mesityl oxide is presumably formed by aldol condensation at the metal center. Reactivity studies of the oxametallacyclobutene complex (PMe3)4Ru(OC(CMe3)CH) showed formation of free ketone upon addition of protic acids and insertion into the metal-oxygen bond upon addition of CO2. The metallacycle was converted to the silyl enol ether upon addition of trimethylsilane and to the free ketone following addition of H-2.
