  Cooperative Thiourea–Brønsted Acid Organocatalysis: Enantioselective Cyanosilylation of Aldehydes with TMSCN

  摘要：

  We report a new thiourea-Bronsted acid cooperative catalytic system for the enantioselective cyanosilylation of aldehydes with yields up to 90% and enamioselectivities up to 88%. The addition of an achiral acid was found to be crucial for high asymmetric induction. Mechanistic investigations using a combination of NMR, ESI-MS, and density functional theory computations (including solvent corrections) at the M06/6-31G(d,p) level of theory suggest that the key catalytic species results from the cooperative interaction of bifunctional thioureas and an achiral acid that form well-defined chiral hydrogen-bonding environments.

• Aryl Radical Activation of C–O Bonds: Copper-Catalyzed Deoxygenative Difluoromethylation of Alcohols

  direct use of free alcohols without purification of the xanthate esters. Mechanistic studies are consistent with the hypothesis of aryl radicals being formed and initiating the cleavage of the C–O bonds of xanthate esters, to generate alkyl radicals as the key intermediates. This aryl radical activation approach represents a new strategy for the activation of alcohols as cross-coupling partners.

  鉴于其在天然产物和药物中的普遍存在，醇是构建 C-C 键最有吸引力的起始材料之一。我们在此报告了第一个利用芳基的反应性来激活醇衍生的黄原酸酯中的 C-O 键的催化策略，从而发现了第一个催化脱氧二氟甲基化反应。在铜催化条件下，很容易从醇原料合成的各种烷基黄原酸酯被催化生成的芳基活化，并通过烷基中间体转化为烷基二氟甲烷产物。这种可扩展的协议具有广泛的底物范围和官能团耐受性，能够对复杂的药剂进行后期修饰。已开发出一种一锅法，允许直接使用游离醇而无需纯化黄原酸酯。机理研究与芳基自由基形成并引发黄原酸酯的 C-O 键断裂以产生作为关键中间体的烷基自由基的假设一致。这种芳基自由基活化方法代表了一种将醇作为交叉偶联物活化的新策略。

The recorded spectral data show that the structure originally attributed to gobienine A is incorrect and that it is not the epimerization‐prone ester site on the butanolide ring that is the locus of misassignment; rather

  A series of unsymmetric salen ligands derived from 1,2-diaminocyclohexane bearing an appended Lewis base on the three-position of one aromatic ring were synthesized by the reaction of various functional salicyaldehydes with the condensation product of 1,2-diaminocyclohexane mono(hydrogen chloride) and 3,5-di-tert-butylsalicylaldehyde. These ligands in conjunction with Ti(OiPr)4 exhibited excellent activity in catalyzing the cyanosilylation of aldehydes with trimethylsilyl cyanide (TMSCN) at mild conditions. The highest activity was observed in the catalyst system with regard to the salen ligand bearing a diethylamino group, which proved to be active even at a high [aldehyde]/[catalyst] ratio up to 50000. In a low catalyst loading of 0.05 mol%, the quantitative conversion of benzaldehyde to the corresponding cyanosilylation product was found within 10 min. at ambient temperature. An intramolecularly cooperative catalysis was proposed wherein the central metal Ti(IV) is suggested to play a role of Lewis acid to activate aldehydes while the appended Lewis base to activate TMSCN.

  Zr(OBut)4 Can serve as an effective promoter for the Meerwein–Ponndorf–Verley alkynylation of aldehydes and also facilitate MPV type cyanide transfer to aldehyde carbonyls with commercially available acetone cyanohydrin under mild conditions. Based on this finding, a new procedure for asymmetric cyanohydrin synthesis has been developed employing (4R,5R)-2,2-dimethyl-α,α,α′,α′-tetraphenyl-1,3-dioxolane-4

  Zr（OBu t）4可以作为Meerwein-Ponndorf-Verley醛烷基化的有效促进剂，并在温和的条件下用市售丙酮氰醇促进MPV型氰化物转移至醛羰基。基于这一发现，开发了一种新的合成不对称氰醇的方法，该方法采用了（4 R，5 R）-2,2-二甲基-α，α，α'，α'-四苯基-1,3-二氧戊环-4， 5-二甲醇（TADDOL，6）作为手性配体。例如，用Zr（OBu t）4顺序处理6（1当量）CH 2 Cl 2溶液（1当量）和丙酮氰醇（2当量）在室温下1小时，随后与3-苯基丙醛在-40°C下反应7.5小时，形成相应的氰醇5g [R = Ph（CH 2）2 ]，分离出的产率为63％，ee为85％。已经用各种醛作为底物阐明了该方法的范围和局限性。
