1.5- Diamino-2-methylpentane

The second group is represented by the following copolyamide, MT, obtained from the condensation of fere-phlhalic acid onto 1,5 diamino-2-methylpentane ... 

Cicadapeptins, a family of non-ribosomal peptides isolated from the fermentation extracts of Cordyceps heteropoda, an ento-mopathogenic fungus from an Australian cicada. The structures of the two major components, cicadapeptin I and II, have been elucidated. Both peptides are acylated at the N-terminus by w-decanoic acid and amidated at the C-terminus by 1,2-diamino-4-methylpentane. The sequence...

On treatment with periodate, the third ozonolysis product, 3-methyloctane-l,7,8-triol(32), yielded formaldehyde [(21)] and 5-methyl-7-hydroxyheptanal (33). The hydroxyaldehyde 33 was oxidized by chromium trioxide to 3-methylpimelic acid (34). Schmidt degradation of the latter gave carbon dioxide [C(14) and C(20)] and l,5-diamino-2-methylpentane (35) (isolated as dipicrate). Kuhn-Roth oxidation of octanetriol (32) yielded one equivalent of acetic acid [C(16) and 16-methyl].
