C]acetoacetate reacted with the a,/3-unsaturated aldehyde 316 to give the methyl 5-hydroxy-3-oxo-6-[3- C]heptenoate derivative 317. Its reduction with NaBHU in the presence of diethylmethoxyborane and saponification provided the corresponding jyn-3,5-dihydroxy-6-heptenoic acid ([ C]fluvastatin, 318) in 40% overall radiochemical yield. [Pg.353]

Cell extracts of A. calcoaceticus SC 13876 in the presence of NAD, glucose, and glucose dehydrogenase reduced 55 to the corresponding monohydroxy compounds 58 and 59 [3-hydroxy-5-oxo-6-(benzyloxy)hexanoic acid ethyl ester 58, and 5-hydroxy-3-oxo-6-(benzyloxy)hexanoic acid ethyl ester 59]. Both 58 and 59 were further reduced to 3S,4R)-dihydroxy compound 56a by cell extracts (Fig. 16). The reaction yield of 92% and an e.e. of 99% were obtained when the reaction was carried out in a 1-L batch using cell extracts at 10 g/L substrate concentration. Product 56a was isolated from the reaction mixture in... [Pg.100]
