Seven new unstable tetramic acid derivatives, cladosporiumins I-O (<b>1</b>⁻<b>7</b>), together with the known analogue cladodionen (<b>8</b>) were isolated from the extract of the deep-sea-derived fungus <i>Cladosporium sphaerospermum</i> EIODSF 008. Their structures were elucidated by spectroscopic analysis, quantum chemical calculations and ECD spectra. Compound <b>4</b> was a Mg complex of tetramic acid derivative. In acidic solvent, <b>4</b> could change to <b>1</b> and <b>6</b>, and <b>7</ ...[more]
