Under carbonylative conditions, neutral Rh(I)-systems modified with weak donorligands (AsPh3 or 1,4-oxathiane) undergo N-Cbz, N-benzoyl, or N-Ts directed insertion into the proximal C–C bond of aminomethylcyclopropanes to generate rhodacyclopentanone intermediates. These are trapped by N-tethered alkenes to provide complex perhydroisoindoles.

A process for the preparation in high yields and purity of the compound 6-(7-((l-aminocyclopropyl)methoxy)-6-methoxyquinolin-4-yloxy)-N-methyl- 1 -naphthamide of formula (I) and of the pharmaceutically acceptable salts thereof is described. The process has various advantages over those previously described, in particular it avoids the use of acyl azide intermediates and their Curtius rearrangement. Novel intermediates useful for the preparation of compound (I) are also described.
selected cyclopropanes as model substrates since they present a relatively weak σ-bond. Herein, we describe an iridium-catalyzed hydroboration of cyclopropanes, resulting in β-methyl alkylboronates. These unusually branched boronates can be derivatized by oxidation or cross-coupling chemistry, accessing "designer" products that are desired by practitioners of natural product synthesis and medicinal chemistry

cycloaddition with tethered alkenes to provide stereochemically complex N-heterocyclic scaffolds. These processes rely upon the generation and trapping of rhodacyclopentanone intermediates, which arise by regioselective, Cbz-directed insertion of Rh and CO into one of the two proximal aminocyclopropane C-C bonds. For cyclizations using cationic Rh(I)-systems, synthetic and mechanistic studies indicate that rhodacyclopentanone
在暴露于中性或阳离子 Rh(I)-催化剂体系后,氨基取代的环丙烷与系链烯烃发生羰基化环加成反应,以提供立体化学复杂的 N-杂环支架。这些过程依赖于环戊酮中间体的产生和捕获,其通过区域选择性、Cbz 定向将 Rh 和 CO 插入到两个近端氨基环丙烷 CC 键之一中而产生。对于使用阳离子 Rh(I) 系统的环化,合成和机理研究表明,环戊酮的形成是可逆的,并且烯烃插入步骤决定了产物的非对映选择性。这种机制有助于对烯烃系链上的取代基进行高水平的立体控制。
