Efficient Entry into 2-Substituted Tetrahydroquinoline Systems through Alkylative Ring Expansion: Stereoselective Formal Synthesis of (±)-Martinellic Acid
new efficient synthesis of 2-substituted tetrahydroquinolines has been achieved by the domino reaction of N-indanyl(methoxy)amines, which consists of three types of reactions: elimination of an alcohol, the rearrangement of an aryl group, and the addition of an organolithium or magnesium reagent. The synthetic utility of this approach is demonstrated by the stereoselective formal synthesis of (±)- martinellic

This invention relates to compounds that inhibit E1 activating enzymes, pharmaceutical compositions comprising the compounds, and methods of using the compounds. The compounds are useful for treating disorders, particularly cell proliferation disorders, including cancers, inflammatory and neurodegenerative disorders; and inflammation associated with infection and cachexia.
A highly para‐selective CAr−H difluoromethylation of ketoxime ethers under ruthenium catalysis has been developed. A wide variety of ketoxime ethers are compatible with the reaction, which leads to the corresponding para‐difluoromethylated products in moderate to good yield. A mechanistic study clearly showed that chelation‐assisted cycloruthenation is the key factor in the para selectivity of the
已经开发了在钌催化下酮肟醚的高度对位选择性C Ar -H二氟甲基化。各种各样的酮肟醚均可与该反应相容,从而以中等至良好的产率产生相应的对二氟甲基化产物。一项机理研究清楚地表明,螯合辅助的环化钌是影响酮肟醚二氟甲基化对位选择性的关键因素。使用密度泛函理论来获得对位选择性的理论理解。#
Dimethylzinc-Mediated Chlorolactamization of Homoallylic Amines with Chloroform
A novel chlorolactamization reaction of homoallylicamines has been developed. The treatment of homoallylicamines with dimethylzinc in chloroform led to the formation of the corresponding β-chlorolactams via the Prins-type cyclization of a carbamoyl chloride intermediate. The results of this study highlight the synthetic utility of chloroform as a source of both carbonyl group and chloride anion.
