Title
(EN) Eribulin intermediates and preparation method thereof
(ZH) 一种艾日布林中间体及其制备方法
Abstract
(EN) The invention relates to Eribulin intermediates and a preparation method thereof. Particularly, the invention relates to compound shown in a formula II, formula III and formula V, wherein Ar is a C1-10 alkyl substituted or alkyloxy substituted or unsubstituted aryl group, R1 and R2 are aldehyde acetal protecting groups or thioacetal protecting groups, R3 is hydrogen or a hydroxy protecting group,and X is halogen or a leaving group. The invention particularly relates to the preparation method of the compounds shown in the formula II, formula III and formula V. The preparation method has the advantages of mild reaction conditions, high selectivity, easy purification, low synthesis cost and the like, and is suitable for large-scale production.
