  Anomalous lumbrical muscles arising from the deep surface of flexor digitorum superficialis muscles in man

  摘要：

  During anatomy practice in 1999 at Kumamoto University School of Medicine, the anomalous lumbrical muscles originating in the forearm were observed in both arms of a cadaver. These muscles, originating from the intermediate tendon of the deep layer of the flexor digitorum superficialis for the index finger (FDS-II), passed through the carpal tunnel to join the insertion of the first lumbrical muscle, and formed a muscle belly near the origin in the left and at the insertion in the right. The left anomalous muscle was innervated by a branch of the median nerve just proximal to the carpal tunnel. The right one received a twig from the nerve to the first lumbrical muscle. Tracing the nerve fibers by peeling off the epi- and perineurium clarified that the nerve fibers supplying the left anomalous muscle formed a common bundle with the fibers to the first lumbrical muscle. Therefore, these anomalous muscles are considered to be the accessory lumbrical muscles arising from the forearm. The three accessory lumbricalis, including one case reported by Yamada (1986), received branches which had slightly different origins from proximally (nerve to the distal belly of FDS-II) to distally (nerve to the first lumbricalis). Accordingly the position of the muscle belly shifted distally. The occurrence of these unusual accessory lumbrical muscles indicates that the distal belly of FDS-II and the first lumbricalis are derived from a common muscle origin and presents an important clue to the phylogenetic origin of the flexor digitorum superficialis.

  with simpler amines through the borrowing hydrogen methodology, producing a variety of substituted secondary and tertiary benzylamines in moderate to excellent yields for the first time with an iron catalyst. Notably, we explore the versatility of this methodology in the one-pot synthesis of nonsymmetric tertiary amines, sequential functionalization of diols with distinctly different amines, and the synthesis

  苄胺在许多药物活性化合物中起着重要作用。因此，开发新颖，可持续的催化方法以提供进入这些特权结构基序的途径至关重要。本文中，我们描述了使用定义明确的均相铁络合物构建多种苄胺的系统研究。该方法包括通过借用氢方法将容易获得的苯甲醇与简单胺直接偶联，用铁催化剂首次以中等至极好的收率生产各种取代的仲和叔苄胺。值得注意的是，我们探索了这种方法在非对称叔胺的一锅合成中的多功能性，具有明显不同胺的二醇的顺序官能化，N-苄基哌啶通过各种合成途径。另外，实现了将可再生结构单元2，5-呋喃-二甲醇直接转化为药学上相关的化合物。

  the N‐alkylation of ammonia (or its surrogates) and amines with “primary” alcohols. On the other hand, the N‐alkylation of ammonia surrogates (i.e., urea and NH4HCO3) with “secondary” alcohols selectively produced the corresponding symmetrically substituted “secondary” amines, even in the presence of excess amounts of alcohols, which is likely due to the steric hindrance of the secondary alcohols and/or

  易于制备的厌氧条件下，可以有效地促进氨（或其替代物，如尿素，NH 4 HCO 3和（NH 4）2 CO 3）和胺与醇（包括伯醇和仲醇）的N-烷基化反应。廉价的负载型氢氧化钌催化剂Ru（OH）x / TiO 2。氨（或其替代物）和胺与“伯”醇的N烷基化反应可以合成各种类型的对称和不对称取代的“叔”胺。另一方面，氨代用品（即尿素和NH 4）的N烷基化HCO 3）与“仲”醇选择性地产生相应的对称取代的“仲”胺，即使在存在过量的醇的情况下，这很可能是由于所产生的仲醇和/或仲胺的空间位阻所致。在有氧条件下，腈可以直接由醇和代理氨合成。观察到的当前N烷基化反应的催化本质上是非均相的，并且回收的催化剂可以重复使用而不会显着降低催化性能。当前的催化转化将通过连续N次进行烷基化反应，其中醇充当烷基化试剂。根据氘标记实验，建议在N烷基化反应期间形成二氢化钌。

  Manganese(III) porphyrin chloride complexes have been developed for the first time as catalysts for the acceptorless dehydrogenative coupling of alcohols and amines. The reaction has been applied to the direct synthesis of imines, tertiary amines and quinolines where only hydrogen gas and/or water are formed as the by‐product(s). The mechanism is believed to involve the formation of a manganese(III) alkoxide
