摘要： The present invention provides novel methods for the asymmetric synthesis of (S)-6-chloro-4-cyclopropylethynyl-4-trifluoromethyl-1,4-dihydro-2H-3,1-benzoxazin-2-one of formula (VI-i) which is useful as a human immunodeficiency virus (HIV) reverse transcriptase inhibitor. In an embodiment, the present invention provides a process for the preparation of an amino alcohol compound of formula (V-i) comprising adding a toluene solution of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone to a toluene solution of a compound of formula (III-i), via a compound of formula (IV-i).

摘要： Novel crystalline forms of two indole compounds connected to phenoxyalkylcarboxylic acid groups are selective PPAR gamma partial agonists that are useful in the treatment of type 2 diabetes, hyperglycemia, obesity, dyslipidemia, and the metabolic syndrome. The novel crystal forms include a crystalline free acid dihydrate and crystalline free acid anhydrate of one compound and several crystalline forms of the free acid and the sodium salt of the second compound. The invention also relates to pharmaceutical compositions comprising these novel crystal forms, processes to prepare the crystal forms and their pharmaceutical compositions, and uses of the crystal forms in the treatment of type 2 diabetes and other PPAR gamma modulated diseases.
