Article abstract of DOI:10.1016/S0040-4039(99)01622-6

Treatment of ascomycin or its O-TBDMS-derivatives with hydrogen sulfide and pyridine in dimethylformamide solution results in deoxygenation reactions at the tricarbonyl sequence of the binding domain. 9-deoxo-ascomycins (5a-c) are obtained in high yields
