One-pot asymmetric cyclocarbohydroxylation sequence for the enantioselective synthesis of functionalised cyclopentanes

A new method has been developed for the enantioselective synthesis of highly functionalised cyclopentanes bearing up to three stereogenic centres with very high stereoselectivity. This one-pot process combines an enantioselective organocatalytic Michael addition with a highly diastereoselective [3+2]-cycloaddition- fragmentation step.
