enantioselective formal [4+2] cycloadditions of 3‐nitroindoles are presented. By using 3‐nitroindoles in combination with an organocatalyst, chiral dihydrocarbazole scaffolds are formed in moderate to good yields (up to 87 %) and enantioselectivities (up to 97 % ee). The reaction was extended to include enantioselective [4+2] cycloadditions of 3‐nitrobenzothiophene. The reaction proceeds through a [4+2] cycl

The compounds of the invention are modulators of cannabinoid receptors CB1 or CB2. The compounds can be used for the prevention or treatment of, e.g., pain, cancer, skin diseases, weight-associated disorders, chemical addictions, psychiatric disorders, neurodegenerative disorders, bone diseases, and inflammatory diseases. The compounds of the invention can further be used to study these diseases and disorders, as well as cannabinoid receptor biology, by coupling the compounds to, e.g., imaging agents.
An efficient metal-free C–H sulfenylation process at the C2 position of non-protected indoles has been developed.
一种高效的无金属C-H砜基化过程已经在非保护吲哚的C2位置上开发出来。

2-(2-Haloalkenyl)-aryl halides, conveniently prepared in a single step from the corresponding o-halobenzaldehydes, are combined with amines under Pd catalysis to provide 1-substituted indoles. All combinations of Br and Cl leaving groups can be employed, and a range of substituents on the arene, alkene and amine, can all be tolerated. The use of 1,3-dichloro-substituted arenes allows a third amination
