标题 :Process for synthesis of FK-506 intermediates
发明人：VOLANTE RALPH P; ASKIN DAVID; SHINKAI ICHIRO; RYAN KENNETH M
权利人:MERCK & CO INC
摘要:A process is described for the synthesis of diastereomeric 2-methyl-4-hydroxy-5-protected-hydroxy-hept-6-en-prolinolamides, which are useful as intermediates in the synthesis of the C10-C18 chain of the macrolide structure for the immunosuppressant FK-506. These compounds are also useful as intermediates for preparing lactone ultraviolet radiation absorbers.

权利人:E I DUPONT NEMOURS AND COMPANY; COMMW SCIENT IND RES ORG
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.
