Dehydromenthofurolactone (tonkafuranone) and other bicyclic lactones are common flavour compounds and can be found in a variety of plants. Herein, we present an improved synthesis of the natural product and a series of close analogues, in combination with efficient purification methods for simple preparation from cheap and easily accessible chemicals. A two‐step, one‐pot, reaction procedure, consisting...
A simple and robust CZE method was developed for the separation and quantification of the antimalarial compound amodiaquine as well as three of its synthetic impurities at a concentration equal to or lower than 0.5%. For capillary electrophoresis, a fused‐silica capillary, a background electrolyte of 100 mM sodium phosphate buffer at a pH value of 6.2, a voltage of +20 kV, and a detection wavelength...
