Recently we reported a new method for the substitution of an hydroxy-or methoxy-group on the bridgehead carbon atom in the bicyclo[2.2.2]octane series by halogens (I), using various halogenating agents [e.g. POCl3, SOC12, PBr3 and also alkali chlorides, bromides or iodide8 (2)] in the presence of po

As part of a study of the elucidation of biochemical and biological properties of pseudo-sugars', replacement of the hexopyranosyl residues of biologically active disaccharides with structurally related pseudo-sugars has been investigated. Trehalosamine\* (1) is an aminoglycoside antibiotic3 produce
A series of triorganotin (4H-1,2,4triazol-4-yl)benzoates have been synthesized by the reaction of 4-( 4H-1,2,4-triazol-4-yl)benzoic acid and 3-(4H-1,2,4-triazol-4-yl)benzoic acid with (R 3 Sn) 2 O (R = Et, n-Bu and Ph) or R 3 SnOH (R = p-tolyl and cyclohexyl). The molecular structure of tri( p-tolyl
