A convenient de novo synthesis of functionalised 2,4,6,8-tetraoxaadamantanes
Abstract
Trioxabicyclononadienes 2 and 4, easily obtained by addition of nucleophiles to the stable α-oxoketene 1, are transformed into the corresponding 2,4,6,8-tetraoxaadamantanes 3 and 5 in high yields by acid-catalysed hydrolysis.
