Title: determining stucture
Post by: jcjones8 on December 09, 2015, 03:54:59 PM

evanomycin, C7H8O3 is very unstable acid isolated from a certain type of bacteria.

evanomycin displays peaks in the IR region at: 3450(br), 1710, 1639, and 886 cm-1

evanomycin absorbs H2 to give a different acid [IR 3450(br), 1739, 1710]

ozonolysis of evanomycin yields formaldehyde and an acid, which on further oxidation with kmno4 gives glutaric acid.

what is the structure of evanomycin?

Forum rules require that we do not answer homework assignments as such, but we can point out errors of thinking or of fact.

Suppose you run us through your reasoning as to structure, and we'll confirm, or not.

Ok let me help you in first step
start with degrees of unsaturation in the compound...
