摘要：

Syntheses with Aliphatic Dialdehydes. XLIV. — Chiral Pentamethine Cyanine Dyes and Heterocycles from Derivatives of (S)‐(+)‐2‐sec‐Butylmalonaldehyde 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).
