Structure-activity dependency of new bacterial tryptophanyl tRNA synthetase inhibitors

Analogues of the aminoacyl tRNA synthetase inhibitor, indolmycin, have been synthesised in which the side chain methyl group is replaced by a wide range of substituents. Their antibacterial and enzyme inhibitory potency is related to steric properties and

Total synthesis of (±) indolmycin

A practical and short synthesis of a novel antibiotic, (±) indolmycin, has been accomplished. The overall process requires only 4 chemical steps by starting from gramine derivative 3 and oxazolinone 2.

New Total Synthesis of (+/-)-Indolmycin

A convergent total synthesis of the antibiotic (+/-)-indolmycin (1) is presented.N-Carbobenzoxy-3-(1-chloroethyl)indole (12) is prepared in three steps from indole-3-carboxaldehyde (9).Alkylation of the lithium anion of 2-(dimethylamino)-4(5H)-oxazolone (4) with chloride (12) provides a mixture of the (+/-)-2-dimethylamino derivative of indolmycin (13) and its diastereomer (14) in a ratio of 2.2:1.Amine exchange is effected by treatment of 13 with methylamine, affording (+/-)-1 in five steps from commercially available 9.Efforts to extend this technology toward an asymmetric synthesis of (-)-1 are described.
