权利人:COUNCIL SCIENT IND RES
摘要:The invention discloses a novel analogues of Angiopterlactone B of formula (I) and process for the synthesis thereof. Further the present invention discloses a total synthetic one pot process for the synthesis of Angiopterlactone B and its analogues comprises the reaction of the dihydro pyronones with Tetra-n-butylammonium fluoride (TBAF) in dry solvent for the time period ranging from 1-2 hours at the temperature ranging from 20-30°C, working up and subjecting the residue to column chromatography to obtain the product.

摘要:The present invention relates to a process for the preparation of enantiomerically enriched cyclobutylamines of formula (I) from α-tertiary cyclobutanones and reacting said enantiomerically enriched cyclobutylamines to enantiomerically enriched cyclobutylamides. Such compounds are useful intermediates in the synthesis of microbiocidal thiazole compounds.

摘要:A method for making discodermolide and analogs thereof. The method utilizes three precursors which correspond to three subparts of discodermolide which are formed by disconnecting the discodermolide carbon backbone at positions C-7 to C-8 and C-15 to C-16. Coupling of the precursors is accomplished using chelation-controlled alkylation.
