The indoline fragment was oxidized into the indole fragment to give (2S,4S)-4-(indol-1-yl)-5-oxoproline; reduction of the carbonyl groups with BH3 yielded (2S,4S)-4-(indol-1-yl)prolines and (2S,4S)-2-hydroxymethyl-4-(indol-1-yl)pyrrolidines. Reduction of (2S,4S)-4-arylamino-5-oxoprolines with BH3 to the corresponding (2S,4S)-4-arylaminoprolines and (2S,4S)-4-arylamino-2-hydroxymethylpyrrolidines was studied \\\\Expert2\\nbo\\Russian Chemical Bulletin\\2011, 60 (5), 873-881.pdf |
