Syntheses of artilide fumarate, its (S) enantiomer and the (R) and (S)
enantiomers of ibutilide fumarate were achieved by reduction of the p
rochiral ketones with (+) and (-)-B-chlorodiisopinocampheylborane. Sev
eral methods for analyzing the optical purity of these compounds are p
resented. The absolute configurations were established by a single cry
stal X-ray crystallographic analysis of o)-1-hydroxy-4-oxobutyl]phenyl
]methanesulfonamide. (C) 1996 Elsevier Science Ltd
