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-potprocess combines an enantioselective organocatalytic Michael addition with a highly diastereoselective [3+2]-cycloaddition-fragmentation step.
