Synthesis and organoleptic properties of p-menthane lactones
Gaudin, Jean-Marc
, p. 4769 - 4776 (2007/10/03)
The stereoselective synthesis and organoleptic properties of p-menthane lactones 7a-h are described. Apart from correcting the published data concerning these compounds, this work has also allowed an unambiguous identification of 7a, 7b and 7g in Italo Mi
