摘要:The present invention relates to synthesis of β-amino acid derivatives of formula (I) and its salts of formula (Ia) by a novel process. The process comprises the reduction of a protected or unprotected prochiral β-amino acrylic acid or derivative there of, by using borane containing reducing agents at atmospheric pressure. The resulting racemic β-amino compound is resolved to a pure stereoisomer of formula (I), specifically to (2R)-4-oxo-4-[3-Ctrifluoromethyl)-5,6-dihydrol[1,2,4]triazolo[4,3-alpyrazin-7(8H)-yl]-1-(2,4,4-trifluorophenyl)butan-2-amine. In an embodiment the invention disclosed polymorphic forms of formula (I), phosphate salt of formula (I) and also a Dibenzoyl-L-tartaric acid salt of formula (I).

摘要:The present invention relates to an improved process for the preparation of antitumor drug 'Docetaxel'. The present invention more particulary relates to a short synthesis of docetaxel following a semi-synthetic approach comprising C-13 esterification of a suitably protected 10-deacetylbaccatin III with a suitably protected side chain acid and subsequent deprotections to produce docetaxel. The process described in the present invention comprises (i) reacting 10-deacetylbaccatin III with a heterocyclic compound to produce a novel 7,10-diprotected 10-deacetylbaccatin III (ii) esterifying the C-13 hydroxyl group in the 7,10-diprotected 10-deacetylbaccatin III compound obtained in step (i) with an oxazolidine side chain acid to obtain a novel C-13 coupled adduct (iii) deprotecting the protecting groups at C-7, C-10 & oxazolidine group an intermediate amino alcohol (iv) derivatising the free amine group in the amino alcohol obtained in the step (iii) with di-tert. butyl dicarbonate to get the desired 'Docetaxel' compound.
