Dedicated to Professor Masahiro Murakami (Kyoto University) in recognition of his profound and ingenious contributions to so many aspects of chemical synthesis.
Dysidealactams E and F and dysidealactone B are recently reported marine natural products. Their syntheses from β-cyclocitral are detailed here. The preparation of certain derivatives and analogues of these compounds is also described and single-crystal X-ray analyses of two of these, as well as that of (±)-dysidealactam F, are reported.
