Synthesis of cyclopentane spirohydantoins by aldol cyclisations: An approach to highly substituted α-cyclopentane amino acids

Add time:08/16/2019    Source:sciencedirect.com

Efficient but reversible aldol condensations of 2-azido-5-formyl-1,5-lactones provide short routes to precursors for α-cyclopentane amino acids, some aminopseudosugars and spirohydantoins of cyclopentanes with control of the stereochemistry at all 5 carbons bearing functional groups. The effects of some of the compounds on human liver-glycosidases are described.
