(2R)-2-[[(9H-Fluoren-9-ylmethoxy)carbonyl]amino]-2-methyl-9-decenoic Acid, is a stable antimicrobial peptide, that can be isolated from the venom of wild bee Lasioglossum laticeps.

A new synthetic pathway is described to prepare asymmetrically protected 2,7-diaminosuberic acid. This strategy exploits (acyloxy)alkoxy promoiety as protecting group and RCM reaction using second generation Grubbs catalyst and provides the trans isomer of (2R,7R)-7-(((9H-fluoren-9-yl)methoxy)carbonylamino)-2-(tert-butoxycarbonylamino)-8- methoxy-8-oxooct-4-enoic acid, which was in turn reduced to obtain (2R,7R)-7-(((9H-fluoren-9-yl)methoxy)carbonylamino)- 2-(tert-butoxycarbonylamino)-8-methoxy-8-oxooctanoic acid.
