Acid-catalysed intramolecular C-alkylation rearrangements of βγ-unsaturated diazomethyl ketones. A noval synthetic entry to pentaleno-annelated polycyclic systems
Abstract
A simpl new intramolecular C-alkylation rearrangment reaction of βγ-unsaturated α′-diazo-ketones has been utilized in the incorporation of a funcationalized pentalene moiety into a variety of system.
