First synthesis of polyoxin M

Chiral enolate derived from (4R)-4-tert-butyldiphenylsilyloxymethyl-4-butanolide 10 with lithium hexamethyldisilyazide (LiHMDS) was treated with trisyl azide, followed by addition of TMSCl to give (2S,4R)-2-azido-4-[(tert-butyldiphenylsilyloxy)methyl]-4-b

Stereoselective syntheses of the antibiotics (+)-negamycin and (-)-HON (RI-331)

The stereoselective syntheses of the antibiotics (-)-HON (5-hydroxy-4-oxo-L-norvaline, RI-331) and (+)-negamycin starting from (S)-4-[(Z)-2-(benzyloxycarbonylamino)-2-(tert-butoxycarbonyl)vinyl]-2, 2-dimethyl-1,3-dioxolane and (R)-3-benzyloxycarbonyl-5-[(Z)-2-(tert-butoxycarbonylamino)-2-(methoxy carbonyl) vinyl]-2,2-dimethyl-1,3-oxazolidine, respectively, are described.

Total synthesis of the biphenomycins; II. Synthesis of protected (2S,4R)-4-hydroxyornithines

Improved synthetic methods for the preparation of three differently protected (2S,4R)-4-hydroxyornithine (10, 16, 24) have been developed which obviously can be used for the construction of the other stereoisomers. Formation of the corresponding α,β-dideh

The Synthesis of Biphenomycin B

Biphenomycin B, a highly potent antibiotic against Gram-negative, β-lactam-resistant bacteria, which was previously isolated from culture filtrates of Streptomyces griseorubiginosus No. 43708, has now been synthesized.
