- ALDOSTERONE SYNTHASE INHIBITORS
-
This invention relates to tricyclic triazole analogues of the formula I or their pharmaceutically acceptable salts, wherein the variable are defined herein. The inventive compounds selectively inhibit aldosterone synthetase. This invention also provides for pharmaceutical compositions comprising the compounds of Formula I or their salts as well as to methods for the treatment, amelioration or prevention of conditions that could be treated by inhibiting aldosterone synthetase.

- Remarkable switch in the regiochemistry of the iodination of anilines by N-iodosuccinimide: Synthesis of 1,2-dichloro-3,4-diiodobenzene
-
Direct iodination of anilines by NIS in polar solvents (such as DMSO) affords p-iodinated products with up to >99% regioselectivity. Switching to less polar solvents (such as benzene) in the presence of AcOH inverts this outcome toward dramatically increased or preferential generation of the o-isomers, also with up to >99% regioselectivity. This finding was exploited in the synthesis of 1,2-dichloro-3,4-diiodobenzene. Georg Thieme Verlag Stuttgart - New York.

- Approaches to the synthesis of 2,3-dihaloanilines. Useful precursors of 4-functionalized-1 H-indoles
-
2,3-Dihaloanilines have been proved as useful starting materials for synthesizing 4-halo-1H-indoles. Subsequent or in situ functionalization of the prepared haloindoles allows the access to a wide variety of 2,4- or 2,3,4-regioselectively functionalized indoles in good overall yields. As no efficient synthetic routes to 2,3-dihaloanilines have been described in the literature, different approaches to the preparation of these 1,2,3-functionalized aromatic precursors are now presented. The most general one involves a Smiles rearrangement from the corresponding 2,3-dihalophenols and allows the preparation of 2,3-dihaloanilides in a straightforward and synthetically useful manner.
