  Efficient access to (1H)-isoindolin-1-one-3-carboxylic acid derivatives by orthopalladation and carbonylation of methyl arylglycinate substrates

  摘要：

  The orthopalladation of methyl arylglycinate derivatives has been studied. The reaction proceeds efficiently for different electron-withdrawing and electron-releasing substituents at the aryl ring. The carbonylation of the orthopalladated complexes affords, in a single step, substituted (1H)-isoindolin-1-one-3-carboxylates. These compounds constitute valuable synthetic intermediates and can be transformed diastereoselectively into octahydroisoindole-1-carboxylic acid derivatives, an important scaffold in the synthesis of many biologically active compounds.

  An efficient method for the synthesis of 3-hydroxymethyl isoindolinones via cobalt-catalyzed C(sp2)–H carbonylation of phenylglycinol derivatives using picolinamide as a traceless directing group is demonstrated. The reaction proceeds in the presence of a commercially available cobalt(II) tetramethylheptanedionate catalyst and employs DIAD as a “CO” surrogate. This synthetic route offers a broad substrate

  证明了一种有效的方法，通过使用吡啶甲酸酰胺作为无痕导向基团，通过钴催化的苯基甘醇衍生物的C（sp 2）–H羰基化来合成3-羟甲基异吲哚啉酮。反应在可商购的四甲基庚二酸钴（II）催化剂存在下进行，并使用DIAD作为“ CO”替代物。该合成途径提供了广泛的底物范围，出色的区域选择性以及完全保留了原始立体化学。此外，所开发的方法提供了获取有价值的对映纯3-取代的异吲哚满酮衍生物的途径。

• Triple Role of Phenylselenonyl Group Enabled a One-Pot Synthesis of 1,3-Oxazinan-2-ones From α-Isocyanoacetates, Phenyl Vinyl Selenones, and Water

  Reaction of alpha-substituted alpha-isocyanoacetates with phenyl vinyl selenones in the presence of a catalytic amount of base (DBU or Et3N, 0.05-0.1 equiv) followed by addition of p-toluenesulfonic acid (PTSA, 0.1-0.2 equiv) afforded 4,4,5-trisubstituted 1,3-oxazinan-2-ones in good to excellent yields. Enantiomerically enriched heterocycles can also be prepared using a Cinchona alkaloid-derived bifunctional organocatalyst for the Michael addition step. The phenylselenonyl group served as an activator for the Michael addition, a leaving group and a latent oxidant in this integrated reaction sequence.

  electron-releasing and electron-attracting functional groups at the phenyl ring of the amino acid. In addition, the reaction of phenylglycine derivatives (1a–1f) with methyl acrylate (4a) catalyzed by [Ru(cymene)Cl2]2 (10%) under the same experimental conditions, gives the corresponding 3,N-disubstituted isoindoline-1-carboxylates 5 through CH/NH coupling. Isoindolines 5 are obtained as a mixture of diastereoisomers
