One-Pot Primary Aminomethylation of Aryl and Heteroaryl Halides with Sodium Phthalimidomethyltrifluoroborate
摘要:
A one-pot primary aminomethylation of aryl halides, triflates, mesylates, and tosylates via Suzuki-Miyaura cross-coupling reactions with sodium phthalimidomethyltrifluoroborate followed by deamidation with ethylenediamine is reported.
Novel cyclopentane dicarboxamide sodium channel blockers as a potential treatment for chronic pain
摘要:
A series of new voltage-gated sodium channel blockers were prepared based on the screening lead succinic diamide BPBTS. Replacement of the succinimide linker with the more rigid cyclic 1,2-trans-diamide linker was well tolerated. N-Methylation on the biphenylsulfonamide side of the amide moiety significantly reduced the clearance rate in rat pharmacokinetic studies. (c) 2005 Elsevier Ltd. All rights reserved.
