Concise routes to four orthogonally protected, enantiopure disulfide bridge mimetics are reported. These four dicarba analogues possess an alkyne, an (E)-alkene, a (Z)-alkene, and an alkane as substitutes for the disulfide bridge. Selective deprotection of one of these mimetics is also illustrated.
