  Evolution of a Manufacturing Route to Omarigliptin, A Long-Acting DPP-4 Inhibitor for the Treatment of Type 2 Diabetes

  摘要：

  Development of a convergent synthesis of omarigliptin (MK-3102) suitable for commercial manufacture is described. The target molecule is assembled through a diastereoselective reductive amination of a highly functionalized pyranone, with a mesylated pyrazole followed by deprotection of a Boc group. The synthesis of the pyranone relies on three Ru-catalyzed, reactions : (1) a PKR reduction of a rac-alpha-aminoketone to set the two contiguous stereogenic Centers, (2) a cycloisomerization of bis-homopropargylic alcohol to a dihydropyran, and, finally, (3) a Ru-catalyzed oxidation of a Pyranol to the desired pyranone. The regioselective synthesis of 4 N-Boc-1-mesyl pyrazole fragment was achieved via base promoted mesyl group isomerization to afford 30:1 selectivity. A highlight, of the endgame process development is telescoping a Boc deprotection and reductive amination followed by direct crystallization of the penultimate from the reaction mixture. This avoids handling of an unstable, mutagenic 1-mesylpyrazole BSA salt used in the earlier multikilogram deliveries and improves the overall diastereoselectivity and efficiency of the route.

  氨基甲酸酯保护的α-氨基酸N-羧酸酐的动力学拆分和环状介孔酸酐的不对称化与新型改性金鸡纳生物碱催化剂的手性α-氨基酸和手性半酯的实用合成

  摘要：

  描述了氨基甲酸酯保护的α-氨基酸N-羧基酐（UNCA）的动力学拆分的大规模应用和使用改性金鸡纳生物碱对环状内消旋酸酐的脱对称化。这些不对称反应是在工业规模上合成手性α-氨基酸6和手性半酯2的有效有机催化方法，因为有机催化剂的回收和产物纯化可以通过简单的萃取程序进行，而无需色谱纯化步骤。改性金鸡纳生物碱催化剂（DHQD）2 AQN和（DHQ）2正如邓和同事所报道的，AQN尚不容易获得，因此不适合工业规模的合成。制备了各种O-烷基化的奎尼丁和奎宁衍生物，并筛选了用醇动力学拆分苯丙氨酸UNCA的催化剂。发现容易制备的O-炔丙基奎尼丁（OPQD）和O-炔丙基奎尼丁（OPQ）是高度对映选择性和实用的催化剂。这些新的催化剂施加到的手性炔丙基甘氨酸的合成24和BAY10-8888 / PLD-118，关键中间体26，在工业规模上，通过UNCA的动力学拆分22和环状的desymmetrization内消旋-酸酐25。

Their affinity towards cholera toxin was assessed by weak affinity chromatography, which allowed a systematic evaluation and selection of the best candidates. Affinity could be enhanced up to one or two orders of magnitude over the affinity of the individual pharmacophoric sugar residues.

  The first strategy for bringing about enantioselective azlactone dynamic kinetic resolution to generate orthogonally protected amino acids has been developed. In the presence of a C2‐symmetric squaramide‐based catalyst, benzyl alcohol reacts with novel yet readily prepared tetrachloroisopropoxycarbonyl‐substituted azlactones to generate trapped phthalimide products of significant synthetic interest

  Non-proteinogenic phenylalanine derivatives were efficiently prepared by Rh(I)-catalyzed [2+2+2] cycloaddition reactions between enantiopure and racemic propargylglycine amino acids, with different protective groups, and diynes. Diverse substituents, including tags such as dansyl or dabsyl, were introduced onto the aromatic ring of the amino acid derivatives by selecting the most appropriate diyne
