Japanese Patent JPH0460594

B2

Compounds of the formula wherein R<1>, R<2> and R<3> are independently selected from hydrogen, C1-5 alkyl and Ph; and R<4> is HSO2, (C1-5 alkyl)sulfonyl, PhSO2, PhCOCH2SO2 or ZCH2COO in which Z is CH2I, CCl3, HSO2CH2, (C1-5 alkyl)sulfonylmethyl, PhSO2CH2, Ph or fluorenylmethyl. The compounds illustrated can be prepared by an 11-step process, starting from 4-chloro-3-nitrophenol and ether derivatives thereof. Many of the intermediates in this process are novel and have, as do the illustrated compounds, antibacterial activity. Novel intermediates have the formulae (I), (II), (III) or (IV> wherein R<5> is H, CH3, benzyl, allyl, CH3SCH2, CH3OCH2, CH3O- CH2CH2OCH2, CCl3CH2, (C1-5 alkyl)3 SiCH2CH2 or Ph3SiCH2CH2; R<7> is CH3O, C2H5O, C1-5 alkyl or Ph; X is HSO3, (C1-5 alkyl) SO3, PhSO3, Cl, Br, I or OH; X' is as X (except OH, or CH3COO; X'' is as X, or CH3COO; and Y is H, NO2 or NH2.
