Details of a synthesis of dihydrofurans using γ-substituted chiral allenamides are described here.Some transformations of these dihydrofurans are also examined including a highly stereoselectivedihydroxylation and a rare account of a Lewis acid-mediated removal of an N-acyl substituent atthe anomeric carbon of a tetrahydrofuran ring system. These studies provide further support forthe synthetic utility of allenamides.
