摘要:
A process for the preparation of an aryloxypropanolamine of the formulaAr--OCH.sub.2 CH(OH)CH.sub.2 NH--R Iwherein Ar is a carbocyclic or heterocyclic aromatic group and R is an alkyl or substituted alkyl group having 1 to 6 carbon atoms, characterized in subjecting a compound of the formula ##STR1## to oxidative cleavage to a dialdehyde of the formula ##STR2## which is then made subject to reduction, amination, acetal hydrolysis, and, where required, removal of a nitrogen protective group, to the formation of a compound of formula I, or an acid addition salt thereof, a compound of formula II and the preparation thereof from mannitol.
摘要:
Novel compounds of the formula ##STR1## wherein R is H or CH.sub.3, a process for their preparation, and their use as intermediates in the preparation of pharmaceutically useful compounds, e.g. substituted benzimidazoles containing a pyridine radical, i.a. omeprazole.
摘要:
The invention relates to a chiral selector useful in separating underivatized enantiomers of nonsterodial anti-inflammatory agents, particularly naproxen and other arylacetic acid compounds, and relates to a process for achieving such separation utilizing the chiral selector, which is also useful in achieving the enantiomeric separation of amines, alcohol derivatives, epoxides and sulfoxides. The invention is also directed to an apparatus which comprises the chiral selectors.
