A facile route to imidazol-4-yl anions and their reaction with carbonyl compounds
摘要:
Treatment of N-protected 4-iodoimidazoles 1-3 in CH2Cl2 solution with an ethereal solution of ethyl-magnesium bromide generates the corresponding imidazol-4-yl anions, which react with carbonyl compounds to give carbinols 4-14 in 60-83% yield.

Presently provided are IDO inhibitors of general formulae (VII), (VIII) as shown below and pharmaceutical compositions thereof, useful for modulating an activity of indoleamine 2,3-dioxygenase; treating indoleamine 2,3-dioxygenase (IDO) mediated immunosuppression; treating a medical conditions that benefit from the inhibition of enzymatic activity of indoleamine-2,3-dioxygenase; enhancing the effectiveness of an anti-cancer treatment comprising administering an anti-cancer agent; treating tumor-specific immunosuppression associated with cancer; and treating immunosupression associated with an infectious disease.
The present invention relates to indolinones of general formula ##STR1## wherein R.sub.1 to R.sub.3 are defined in claim 1, the isomers and the salts thereof, particularly the physiologically acceptable salts thereof which have valuable pharmacological properties, particularly an inhibiting effect on various kinases and cycline/CDK complexes and on the proliferation of various tumour cells, pharmaceutical compositions containing these compounds, their use and processes for preparing them.

Tr-protected amines were caught directly out of reaction mixtures by simultaneous cleavage of the protecting group. By releasing the products with ammonia the corresponding free amines were obtained in high yields and purities. The broadly applicable method of simultaneousdeprotection and purificationbased on ionicresincapture was applied for Grignard and Mitsunobu reactions as well as amide formations
