Organic chemist assistance...

[chemwipe]

Does anyone know of any online resource for identifying chemical formulas? I can identify a few functional groups, but definitely having trouble identifying/classifying these compounds:







Or maybe one of you talented organic chemists could assist me or at least point me in the right direction?

Thanks a lot!

These are alpha-aminoacid hydrazides, the alpha-amino group is blocked via an acetate group. I have always disliked nomenclature, and therefore I recommend that you use a biochemistry book to ascertain the aminoacids. if you know how to draw the structures of these, or convert them to smiles you can search for them in a number of sites on the internet.
Generally, searchig for "acyl hydrazides" in google might help also.
