Syntheses and UV/Vis-spectroscopic properties of the chain-substituted, homochiral pentamethine cyanine dyes 16 and 17 are described. 16 and 17 as well as the homochiral five-, six-, and seven-membered heterocycles 11 - 15 are prepared from derivatives (5 and 6) of homochiral (S)-(+)-2-sec-Butylmalonaldehyde (8), the first known chiral malonaldehyde, which in turn is synthesized in a seven-step procedure from homochiral (S)-(-)-2-methyl-1-butanol (1).
