标 题 :Macrocyclization reactions and intermediates and other fragments useful in the synthesis of halichondrin macrolides
发明人：FANG FRANCIS G; KIM DAE-SHIK; CHOI HYEONG-WOOK; CHASE CHARLES E
权利人:EISAI R&D MAN CO LTD
摘要:The invention provides methods for the synthesis of a halichondrin macrolides through a macrocyclization strategy. The macrocyclization strategy of the present invention involves subjecting a non-macrocyclic intermediate to a carbon-carbon bond-forming reaction (e.g., an olefination reaction (e.g., Horner-Wadsworth-Emmons olefination), catalytic Ring-Closing Olefin Metathesis, or Nozaki-Hiyama-Kishi reaction) to afford a macrocyclic macrolide. The invention also provides compounds useful as intermediates in the synthesis of a halichondrin macrolides and methods for preparing the same.

摘要:This invention relates to the synthesis of dithiocarboxylic acid esters by reaction of bis(thioacyl) disulphides, thioacetals or vinylidane bis(thioether) with free-radicals (optionally in the presence of monomers). The invention also relates to processes for the synthesis of polymers utilising these dithioesters as polymerisation regulators (chain transfer agents) or to the use of bis(thioacyl) disulphides to generate dithioester chain transfer agents in situ.
