## Abstract The condensation of 3(5)‐aminopyrazole and 5‐amino‐3‐phenylpyrazole with ethyl 2,4‐dioxopentanoate and 2‐ethoxymethylidene‐3‐oxobutyrate has been re‐investigated. Contrary to previos reports, the former reaction gives rise to both regioisomeric pyrazolo [1,5‐a]pyrimidines (5‐carbethoxy‐

The conformation of thymosin beta 9 in solution of 40% (v/v) 1,1,1,3,3,3-hexafluoro-2-propanol-d2 in water has been investigated by two-dimensional 1H-nmr spectroscopy. Under this condition thymosin beta 9 adopts an ordered structure. The determination of the conformation of the peptide was based on
## Abstract Keto aldoses usually form complex mixtures of equilibrating isomers in solution. This is due to the two different positions that may be used for ring closure in dicarbonyl sugars. The composition of various 2‐keto aldoses **1**–**5** and **8**, the 3‐keto aldose 2‐deoxy‐D‐__erythro__‐he
