Stereoselective synthesis of a new trihydroxyindolizidine lactone
摘要:
A general approach to 1,6,7-trihydroxyindolizidin-8-carboxylates is illustrated through the synthesis of a 7-lactone in an enantiopure form in seven steps starting from (3S)-3-t-butyloxy-1-pyrroline N-oxide and the acetonide of (2E,4S)-4,5-dihydroxy-2-pentenoic acid derived from (S)-malic acid and mannitol, respectively. The process was completely stereoselective and allowed the total control of the relative and absolute configuration of the five contiguous stereocentres of the product. (c) 2005 Elsevier Ltd.

The invention provides a new enantioselective process for the preparation of (S)-pregabalin, or a pharmaceutical acceptable addition acid salt comprising: acid hydrolysis of the dioxolan ring of a chiral compound of general formula (I) to obtain compound of general formula (II); oxidation of compound (II) to obtain a compound of general formula (III) and transforming compound (III) into compound of general formula (IV); subjecting compound (IV) to basic hydrolysis to obtain a compound of general formula (V) which is reduced to obtain enantiomerically pure S-pregabalin. The invention also provides new chiral intermediates involved in the process.
