The synthesis of six single-chain, alkyl-branched bolalipids and first investigations of the lyotropic behaviour of these lipids are reported.
An attempt to synthesize long-chain ω-bromocarboxylic esters from the mixed electrolyses of ω-bromocarboxylic acids and half-esters is described. Methyl 15-bromopentadecanoate was successfully prepared in this way in 37% yield, but other reactions producing methyl 16-bromohexadecanoate (by two different routes) and methyl 14-bromotetradecanoate gave low yields (6–18%) and difficulties in purification of products. The product analysis of these electrolyses (symmetrical and unsymmetrical coupling products, methyl esters of starting materials) is given. It is concluded that this method is more likely to be of specific rather than general use.
