    摘要: A process for preparing &ggr;-hydroxy-4-[[2-oxazolyl]alkyl]-&agr;-[(cyclo)alkyl- or aryl- or heteroaryl-substituted methyl]-2-[[(un)substituted alkyl]aminocarbonyl]-1-piperazinepentanamides is disclosed. The piperazinepentanamides are useful as HIV protease inhibitors. A process for making a 4-[[2-oxazolyl]alkyl]-2-[[(un)substituted alkyl]aminocarbonyl]piperazine by treating a ketoamide precursor with fuming sulfuric acid in the presence of polyphosphoric acid is also disclosed. In addition, a process for enhancing the optical purity of 4-[[2-oxazolyl]alkyl]-2-[[(un)substituted alkyl]aminocarbonyl]-piperazines via the formation 2-naphthalenesulfonic acid crystal salts thereof is disclosed, as well as a method for purifying 2-naphthalenesulfonic acid.

    摘要: This invention relates to crystalline pharmaceutically acceptable salts of an alpha 1a adrenergic receptor antagonist, Compound A, which are useful in the treatment of benign prostatic hyperplasia. Pharmaceutical compositions employing the crystalline salts, and processes for making and using the crystalline salts and pharmaceutical compositions of Compound A are also disclosed. This invention further relates to a process for obtaining enantiomerically pure intermediate useful for the synthesis of end product alpha 1a adrenergic receptor antagonists. The end product compounds are useful for the treatment of benign prostatic hyperplasia and for relaxing lower urinary tract tissue. The invention also relates to a process for preparing a class of dihydropyrimidinone compounds of which Compound A is a member, wherein the process involves deprotonating a dihydropyrimidinone compound and then coupling the deprotonated derivative with a primary amine.

    摘要: A process for preparing cis-(1S,2R)-indanediol is disclosed. The process comprises (A) fermenting a culture medium containing a yeast strain selected from the group consisting of Trichosporon cutaneum MY 1506 (ATCC 74440) and mutants thereof and 1,2-indanedione to form cis-(1S,2R)-indanediol; and (B) recovering cis-(1S,2R)-indanediol from the culture medium. A process for preparing (1S)-amino-(2R)-indanol from the recovered cis-(1S,2R)-indanediol via the Ritter reaction is also disclosed.
