We present here a joint theoretical and experimental study on the oxidation reactivity of glycerol catalysed by chemically pure small Au clusters in the absence and presence of H2O2. From high-resolution mass spectrometry, fruitful products of glycer

Steroids with 4-ene-3,6-dione functionality have application in natural product chemistry, as synthetic intermediates and as aromatase inhibitors. Here, we report a two-phase oxidation of a range of steroidal 5-en-3beta-ols into corresponding 4-ene-3

Oxidation of 20-hydroxyecdysone ( crustecdysone ) (4) with Jones reagent gives a 2:1 mixture of posterone (1) and its 3-keto derivative (2). A possible source of (2) is suggested.
