Asymmetric synthesis of the cyclopentanones related to NCS and N1999A2 antitumor antibiotics

Optically pure protected mono- or dihydroxylated cyclopentanones, precursors for the core of the antitumor antibiotics NCS and N1999A2, 1 and 2, were obtained in six to eight steps with excellent overall yields (up to 52%).
