Diastereoselective synthesis of the 5-hydroxy-pyrrolidinone amino acid of the microsclerodermins and model studies for an end-game strategy for microsclerodermin B
Diastereoselective synthesis of amino acids from the microsclerodermins. A pyrrolidinone amino acid was made by alkene hydration in two steps. Bromination and dehalogenation gives a sensitive hemiaminal amino acid.
