Abstract:
The present invention relates to a process for the preparation of epothilone analogs by initially forming novel ring-opened epothilones and carrying out a macrolactamization reaction thereon. The subject process is amenable to being carried out in a single reaction vessel without isolation of the intermediate compound and provides at least about a three-fold increase in yield over prior processes for preparing the desired epothilone analogs.
Abstract:
The present invention provides a process for preparing compounds of formula (I) ["insert chemical structure here"](I)or a pharmaceutically acceptable salt thereof. The compounds prepared by the process of the invention inhibit tyrosine kinase activity of growth factor receptors such as HER1, HER2 and HER4 thereby making them useful as antiproliferative agents for the treatment of cancer and other diseases.
Abstract:
N-protected-L-homocysteine disulfide of the formula (I) or an activated form thereof is reacted with (S)-2-amino-6,6-dimethoxyhexanoic acid, methyl ester to give the disulfide intermediate of the formula (II). The disulfide intermediate of formula (II) is reacted to cleave the disulfide bond and the resulting monomer is subjected to an acid catalyzed cyclization reaction to give the N-protected lactam of the formula (III). Removal of the N-protecting group gives [4S-(4 alpha ,7 alpha ,10a beta ]-4-aminooctahydro-5-oxo-7H-pyrido[2,1-b][1,3]thiazepine-7-carboxylic acid, methyl ester which along with its salt is useful as an intermediate in the preparation of the dual inhibitor [4S- [4 alpha (R*),7 alpha ,10a beta ]]-octahydro-4-[(2-mercapto-1-oxo-3-phenylpropyl)amino]-5-oxo-7H-pyrido-[2,1-b][1,3]thiazepine-7-carboxylic acid.
