Abstract
Diazo-hydroxy-acylmethanes 3a,b, easily prepared by aldoltype condensation of lithio-diazo-acylmethanes 2 with aldehydes and ketones la,b, are valuable synthetic intermediates able to undergo a range of transformations. It was shown, for example, that 3a,b rearrange by proton acid catalysis or thermolysis with carbon or hydrogen migration.File in questo prodotto:
