Method of making asymmetric de ring intermediates for the synthesis of camptothecin and camptothecin analogs |
| abstract |
Methods of making asymmetric DE ring intermediates for the synthesis of camptothecin and camptothecin analogs employ a dioxane intermediate as the immediate precursor to the DE ring intermediate. Novel intermediates are also disclosed. |
