Intermediates useful in the preparation of halichondrin compounds and methods for preparing the same
The invention relates to intermediates useful in the preparation of halichondrin compounds, methods for preparing the same and use thereof, such as halichondrins, eribulin, or their analogs. The intermediates, the methods and use thereof are used for the synthesis of the C20-C26 fragment of halichondrin compounds. The raw materials in the synthetic route of the invention are cheap and easily obtained, the sources and the qualities of the raw materials are reliable. The choice of the methods useful in the synthesis of chiral central structures are based on the structural characteristics of the reactants, thus effectively improving the synthesis efficiency, reducing the difficulties and risks of product quality control, and avoiding the use of highly toxic and expensive organotin catalysts to significantly decrease costs and improve environmental friendliness.

2-AMINO-N-(AMINO-OXO-ARYL-LAMBDA6-SULFANYLIDENE)ACETAMIDE COMPOUNDS AND THEIR THERAPEUTIC USE
The present invention pertains generally to the field of therapeutic compounds. More specifically the present invention pertains to certain 2-amino-N-(amino-oxo-aryl-λ.sup.6-sulfanylidene)acetamide compounds (referred to herein as ANASIA compounds) that, inter alia, inhibit (e.g., selectively inhibit) bacterial aminoacyl-tRNA synthetase (aaRS) (e.g., bacterial leucyl-tRNA synthetase, LeuRS). The present invention also pertains to pharmaceutical compositions comprising such compounds, and the use of such compounds and compositions, both in vitro and in vivo, to inhibit (e.g., selectively inhibit) bacterial aminoacyl-tRNA synthetase; to treat disorders that are ameliorated by the inhibition (e.g., selective inhibition) of bacterial aminoacyl-tRNA synthetase; to treat bacterial infections; etc.
