Transformation of betulin diacetate by the Prins reaction

The interaction of betulin diacetate with formaldehyde by the Prins reaction in various media was studied. As a result, 3β,28-di- O -acetyl-30-hydroxymethyl-(20)29-lupene, 3β-acetyl-28-hydroxy-(20)29-lupene, and 3β,28-di- O -acetoxy-19-(5′,6′-dihydro-2′ H -pyran-4′-yl)-20,29,30-trinorlupane were obt...
