186   One-pot synthesis of β-diketimine ligands One-pot synthesis of β-diketimine ligands    2010 Symmetric N,N'-dialkyl-2-amino-4-imino-pent-2-enes (nacnacRH) can be prepared in high yields in a simple one-pot reaction from acetylacetone and 2 equiv. of amine. Optimized conditions require the azeotropic removal of water, use of a minimum amount of solvent, and of 1 equiv. of acid. Either para-toluenesulfonic acid, hydrochloric acid, or a mixture of both can be employed, with the latter being most advantageous. Symmetric nacnacRH are thus obtained in higher than 95% purity and with 65% yield... 查看全文

199   Role of Conserved Prolines in the Structure and Function of the Na+/Dicarboxylate Cotransporter 1, NaDC1† Role of Conserved Prolines in the Structure and Function of the Na+/Dicarboxylate Cotransporter 1, NaDC1† Aditya D. Joshi and Ana M. Pajor*    2006 The Na+/dicarboxylate cotransporter 1 (NaDC1) is a low-affinity transporter for citric acid cycle intermediates such as succinate and citrate. The sequence of NaDC1 contains a number of conserved proline residues in predicted transmembrane helices (TMs) 7 and 10. These transmembrane domains are of particular importance because they may be involved in determining the substrate or cation-binding affinity in NaDC1. Four conserved proline residues in TMs 7 and 10 of rabbit NaDC1 were replaced with a... 查看全文
