An improved synthesis of enantiopure 2-azabicyclo[2.2.1]heptane-3-carboxylic acid
摘要:
A facile multigram scale preparation of (1R.3S.4S)-2-azabicyclo[2.2.1]heptane-3-carboxylic acid via stereoselective synthesis of the corresponding alpha-amino ester hydrochloride is detailed. Hitherto applied protocols for the synthesis of this cyclic proline analogue involving a tedious chromatographic purification step could thus be considerably improved upon. The specific rotation of the alpha-amino acid reported in the literature has been revised. (C) 2002 Elsevier Science Ltd. All rights reserved.

The invention relates to 1, 7-diazacarbazole compounds of Formula (I), (I-a) and (I-b) which are useful as kinase inhibitors, more specifically useful as checkpoint kinase 1 (chk 1) inhibitors, thus useful as cancer therapeutics. The invention also relates to compositions, more specifically pharmaceutical compositions comprising these compounds and methods of using the same to treat various forms of cancer and hyperproliferative disorders, as well as methods of using the compounds for in vitro, in situ, and in vivo diagnosis or treatment of mammalian cells, or associated pathological conditions.
