This Latter Reacts With Primary Amides To Yield The Corresponding N,N-Dimethyl-N'-Acylformamidines. Solid State Structure Of N-[(Dimethylamino)Methylene]Phenoxyacetamide (4) Obtained By X-Ray Crystallography Is Also Reported. (C) 1997 Elsevier Science Ltd. Doi:10.1016/s0040-4020(97)10041-2
专利号:US-4922015-A 优先权日:1987-04-08 标 题:Synthesis of peptide amides by means of a solid phase method using acid-labile anchoring groups 发明人:BREIPOHL GERHARD; KNOLLE JOCHEN; STUEBER WERNER 权利人:HOECHST AG 摘要:The invention relates to new compounds of the formula ##STR1## in which R 1 denotes (C 1 -C 8 )-alkyl or optionally substituted (C 6 -C 14 )-aryl, R 2 denotes hydrogen or an amino acid residue which is protected by an amino protective group which can be cleaved off with weak acid or base, R 3 denotes hydrogen or (C 1 -C 4 )-alkyl, and Y 1 -Y 9 denote identical or different radicals hydrogen, (C 1 -C 4 )-alkyl, (C 1 -C 4 )-alkoxy or -O-(CH 2 ) n -COOH (with n=1 to 6), one of these radicals being -O-(CH 2 ) n -COOH. A process for the preparation thereof and the synthesis of peptide amides by means of a solid phase method using these new compounds (spacers) are described.
专利号:US-7022691-B2 优先权日:2002-04-04 标题 :Inhibitors of serine and metallo-β-lactamases 发明人:BUYNAK JOHN D; CHEN HANSONG 权利人:BUYNAK JOHN D; CHEN HANSONG 摘要:Compounds of formula (I): n nwherein R 1 , R 2 , R 3 , R 4 and n have any of the values defined in the specification, and their pharmaceutically acceptable salts, are useful for inhibiting simultaneously serine and metallo-β-lactamase enzymes, for enhancing the activity of β-lactam antibiotics, and for treating β-lactam resistant bacterial infections in a mammal. The invention also provides pharmaceutical compositions, processes for preparing compounds of formula I, and novel intermediates useful for the synthesis of compounds of formula I.
