    Synthesis of a 16-Membered Cyclic Peptide Model of the BCF Rings of Ristocetin A Using Arene-Ruthenium Chemistry Coupled with Cycloamidation
    摘要:
    A convergent synthetic approach to the cyclic peptide 4, which is a model for the B/C/F ring system of ristocetin B, is described. A key reaction is the coupling of the phenolic dipeptide 5, constructed from arylglycine subunits, with the chlorophenylalanine-RuCp cationic complex 6, followed by demetalation of the product to give the diaryl ether 7, without epimerization at any of the amino acid residues. Deprotection of 7 followed by cycloamidation affords the target molecule 4, produced as a mixture of atropdiastereomers which were separated and characterized by NMR spectroscopy.

    摘要:
    与经过充分研究的四氢喹啉的不对称催化合成相反,针对3,4-二氢喹啉-2-酮的不对称方法非常少见。在此,基于协同催化,据报道乙炔基苯并恶嗪酮与乙炔基乙酸和新戊酰氯生成的混合酸酐之间发生首次不对称级联反应。这样就可以形成高吸引力的3,4-二氢喹啉-2-酮,在C3和C4带有两个邻位手性中心,具有非对映和对映选择性。提出了该反应的合理的手性诱导模型。通过去除N保护基团进一步详细说明环化产物,可以证明这种方法的实用性。

    An unprecedented [4+2] cycloaddition of in situ generated azoalkenes with arylacetic acids has been developed under the catalysis of isothiourea. The reaction provided an efficient approach to the synthesis of 4,5-dihydropyridazin-3(2H)-one derivatives in moderate to good yields (up to 95%).

    Isothiourea HBTM-2.1 catalyses the Michael addition–lactonisation of 2-aryl and 2-alkenylacetic acids and α,β-unsaturated trichloromethyl ketones. Ring-opening of the resulting dihydropyranones and subsequent alcoholysis of the CCl3 ketone with an excess of methanol gives a range of diesters in high diastereo- and enantioselectivity (up to 95 : 5 dr and >99% ee).

These products readily undergo N‐ to C‐sulfonyl photoisomerization and are derivatized to afford stereodefined piperidines and tetrahydropyrans.

    A process for the enantioselective synthesis of an (S)— or (R)-1-[2-dimethylamino)-1-(methoxyphenyl)ethyl]cyclohexanol and analogues or salt thereof are described. The method involves the steps of (a) reacting an (S) or (R) 4-benzyloxazolidinone with a mixed anhydride of a methyoxyphenylacetic acid under conditions which form a oxazolidinone, (4S)— or (4R)-4-benzyl-3-[methyoxyphenyl]acetyl]-oxazolidin-2-one, (b) treating the (4S)— or (4R)-4-benzyl-3-[(methoxyphenyl)acetyl]-1,3-oxazolidin-2-one with an aprotic amine base and titanium chloride in a chlorinated solvent under conditions which permit formation of the corresponding anion, (c) mixing the corresponding anion with titanium chloride and cylcohexanone under conditions which permit an aldol reaction to form the corresponding (4S)— or (4R)-4-benzyl-3-[(2R)-2-(1-hydroxycyclohexyl)-2-(methoxyphenyl)acetyl]-1,3-oxazolidin-2-one, (d) hydrolyzing the (4S)— or (4R)-4-benzyl-3-[(2R)-2-(1-hydroxycyclohexyl)-2-(methoxyphenyl)acetyl]-1,3-oxazolidin-2-one to form a chiral acid (2S or 2R)-(1-hydroxycyclohexyl)-methoxyphenyl)acetic acid, (e) coupling the chiral phenylacid to a secondary amine to form an amide, and (f) reducing the amide to form an (S) or (R) 1[2-dimethylamino)-1-(methoxyphenyl)ethyl]cyclohexanol or a salt thereof.

    In contrast to the well‐studied asymmetric catalyzed synthesis of tetrahydroquinolines, the asymmetric methodologies toward 3,4‐dihydroquinolin‐2‐ones are quite rare. Herein, the first asymmetric cascade reaction is reported between ethynyl benzoxazinanones and mixed‐anhydrides generated from aryl acetic acids and pivaloyl chloride, based on synergistic catalysis. This allowed the formation of attractive
