Title:
PREPARATION METHOD FOR INTERMEDIATE OF ECTEINASCIDIN COMPOUND
Document Type and Number:
WIPO Patent Application WO/2024/093091
Kind Code:
A1
Abstract:
The present invention provides a preparation method for preparing an intermediate of an ecteinascidin compound by taking an electrically neutral organic oxidant as a unique auxiliary agent, comprising the steps of dissolving compound A in an organic solvent, adding an electrically neutral organic oxidant, and performing a reaction at 50-70℃ for 1-25 h. The method of the present invention is simple to operate with the reagent used cheap and easy to obtain, and does not need to use other auxiliary agents such as a catalyst to assist the reaction. The method of the present invention can allow for a reaction in a water-containing system, with mild and unharsh reaction conditions, low amount of the solvent used, high yield, and small pollution to the environment, and thus is suitable for industrial production of a key intermediate of an ecteinascidin compound.
