Abstract
1445872 2-Deoxy-streptamine-aminoglycosides PFIZER Ltd 4 June 1974 [5 June 1973] 26719/73 Heading C2C Novel 2-dioxystreptamines and their acid addition salts in which R is an aromatic carboxylic or heterocyclic group, R<SP>1</SP> is hydrogen or methyl R<SP>2</SP> is amino or hydroxy, R<SP>3</SP> is hydrogen or hydroxy. R<SP>5</SP> is hydrogen or a group of Formulµ VI or VII and the dotted line represents an optional bond when each R<SP>3</SP> is hydrogen are prepared by reacting a compound II in which R<SP>2</SP>' is a free or protected hydroxyl group, R<SP>3'</SP> is hydrogen or a free or protected hydroxyl group, R<SP>4</SP> is a mono-valent protecting group for a primary amino group, and R<SP>6</SP> is a free or protected hydroxyl group or a group OR<SP>5'</SP> in which R<SP>5'</SP> is a Group VI or VII in which any free amino group is replaced by NHR<SP>4</SP> and any free hydroxyl group is optionally protected and R<SP>7</SP> is a free or protected hydroxyl group or a compound V with (1) an aldehyde R-CHO are simultaneously or subsequently reducing the Schiffs base so formed (2) a halide R-CH 2 -X where X is halogen or (3) an acylating agent derived from an acid R-COOH and reducing the R-CO group so formed, and thereafter removing any amino or hydroxyl protecting groups. Compounds I prepared are the 6<SP>1</SP>-(R-CH 2 ) derivatives of neamine, kanamycins A and B, tobramycin gentamycins C 1a and C 2 and 3,41- dideoxy-kanamycin B, in which R is phenyl (optionally substituted by Me, OH, NMe 2 , CF 3 , NH 2 , NH-COCH 3 , Ph, CH 2 OH, F, Br, OB 3 , COOH, NO 2 , mono- or di-Cl or mono-, di- or tri-MeO), naphthyl, phenanthryl, furyl, thienyl (optionally substituted by Me) pyrrolyl, indolyl or pyridinyl (optionally substituted by Cl). Compounds I have anti-bacterial activity and form with a carrier a pharmaceutical composition which may be administered orally or parenterally.
