PCT No. PCT/EP96/00407 Sec. 371 Date Jul. 31, 1997 Sec. 102(e) Date Jul. 31, 1997 PCT Filed Feb. 1, 1996 PCT Pub. No. WO96/24607 PCT Pub. Date Aug. 15, 1996The present invention refers to basic amides derivatives of GE 2270 and GE 2270-like antibiotics of general formula (1), wherein the group GE represents the antibiotic core molecule. The amide derivatives of antibiotic GE 2270 of formula (I) are antimicrobial agents mainly active against gram positive bacteria.

Complexes of t-BuLi monomer with 1,4,7-trimethyl-1,4,7-triazacyclononane (TMTAN, 3-CH3) and tris(N,N-dimethyl-2-aminoethyl)amine (4-CH3) were identified by 13C-NMR. Rapid elimination of LiN(CH2CH2NMe2)2 takes place from the free CH2CH2NMe2 group of t-BuLi·4-CH3. BuLi complexes of hexamethyltriethylenetetramine (5-CH3) and octamethylpenthaethylenehexamine (6) behave similarly, as does 4-CH2Li. Complexes of BuLi oligomers are lithiated at free N-CH3.

N-lithio-N,N',N'',N''-tetramethyldiethylenetriamine (I-Li) is formed from 2,5,8,11-tetramethyl-2,5,8,11-tetraazadodecane (III) or from 2,5,8,11,14,17- hexamethyl-2,5,8,11,14,17-hexaazaoctadecane (IV) with n-BuLi or sec-BuLi, respectively, its isomer N'-lithio-N,N,N'',N'',-tetramethyldiethylene- triamine (II-Li) from tris(2-dimethylaminoethyl)amine (V) with n-BuLi. IV results from treatment of N-lithiomethyl-N,N',N'',N''- tetramethyldiethylenetriamine (PMDTA-Li) with 1,2-dibromoethane.
