CRYSTALLINE DERIVATIVES OF (S)-1-((2R,3R,4S,5S)-5-ALLYL-3-METHOXY-4-(TOSYLMETHYL)TETRAHYDROFURAN-2-YL)-3-AMINOPROPAN-2-OL

Disclosed are salts of a compound of formula 1, as shown below, where R1, R2, R3, R4, R5, R6 and R7 are as described herein. Also, disclosed is a process for the preparation of the salts of the compounds of formula 1, and intermediates used therein. The salts of the compound of formula 1 can be useful for preparation of halichondrin analogs such as eribulin.

Early introduction of the amino group to the C27-C35 building block of Eribulin

A new synthetic strategy towards the C27-C35 subunit of Eribulin (1) has been devised to include a protected 1,2-amino alcohol at C34-C35. Early introduction of the C35 amino group in the synthesis of 1 increases the efficiency of the route. This new approach can be accomplished on a multi-gram scale and allows for the successful synthesis of Eribulin.
