Standardmethoden synthetisiert. Durch dynamische Differenzkalorimetrie DSC wurden der Schmelzpunkt und die Schmelzenthalpie der einzelnen Verbindungen erhalten. Mittels HPLC wurde die Sättigungskonzentration in Wasser bestimmt. Der Verteilungskoeffizient Octanol/Wasser wurde nach Rekker und Mannhold berechnet und der Rm‐Wert durch RP‐DC bestimmt. Die beiden letzten Parameter lassen sich mit hoher Signifikanz

A set of chiral crystal solids with odd and even numbers of carbon atoms based on S-naproxen, ester S-naproxen-R1 (R1 = H, methyl, ethyl, n-propyl, n-butyl, and n-amyl), has been prepared, alternatively crystallizing in the space groups P21 and P212121, respectively, which shows the multi odd–even effects on cell parameters, meltingpoints, and optical properties.
