As was anticipated based on mechanistic reasoning, bis-nucleophilic o-(arylamino)methyl phenols underwent a facile, base-promoted cyclocondensation with reactivity matched bis-electrophilic (hetero)aromatic substrates to give a rare type of substituted di

Herein, we broaden the application scope of (cyclo-pentadienone)iron complexes 1 in C=N bond reduction. The catalytic scope of pre-catalyst 1b, which is more active than the “Kn?lker complex” (1a) and other members of its family, has been expanded to the catalytic transfer hydrogenation (CTH) of a wider range of aldimines and ketimines, either pre-isolated or generated in situ. The kinetics of 1b-promoted CTH of ketimine S1 were assessed, showing a pseudo-first order profile, with TOF = 6.07 h–1 at 50 % conversion. Moreover, the chiral complex 1c and its analog 1d were employed in the enantioselective reduction of ketimines and reductive amination of ketones, giving fair to good yields and moderate enantioselectivity.

A series of novel substituted 3,4-dihydro-2H-1,3-benzoxazines were prepared in moderate to good yields by aza-acetalizations of aromatic aldehydes with 2-(N-substituted aminomethyl)phenols in the presence of chlorotrimethylsilane or SnCl4. It w
