position‐selective polyhalogenation of aliphatichydrocarbon bonds is presented. The reaction proceeded within the Hofmann‐Löffler manifold with amidyl radicals as the sole mediators to induce selective 1,5‐ and 1,6‐hydrogen‐atom transfer followed by halogenation. Multiple halogenation events of up to four innate C−H bond functionalizations were accomplished. The broad applicability of this new entry into polyhalogenation
The synthesis and biological activities of biarylamide-substituted diaminoindanes as microsomal triglyceride transfer protein (MTP) inhibitors are described. One of the more potent compounds, 8aR, inhibited both the secretion of apoB from Hep G2 cells and the MTP-mediated transfer of triglycerides between synthetic acceptor and donor liposomes with IC50 values of 0.7 and 70 nM, respectively. In normolipidemic rats and dogs, oral administration of 8aR dose-dependently reduced both plasma triglycerides and total cholesterol. Moreover, in rats and dogs, 8aR also prevented the postprandial rise in plasma triglycerides following a bolus administration of a fat load. Because MTP inhibitors decrease very low density lipoprotein assembly in the liver, the potential for hepatic lipid accumulation was evaluated. In normolipidemic rats, hepatic cholesterol and triglyceride contents were dose-dependently increased by 8aR. However, hepatic lipid accumulation resulted in negligible change in total liver weight and was reversible after withdrawal of the compound.
