Sweeney, Edward E. (University of California, Los Angeles) and Gregory J. Jann. Utilization of carbohydrates and polyhydric alcohols by Mycobacterium tuberculosis. J. Bacteriol. 84:459-465. 1962.-A new procedure, using a massive inoculum and nongrowth basal medium, was employed for testing carbohydrate and polyhydric alcohol utilization by human tubercle bacilli. A positive reaction was represe...

Aldehydes undergo smooth conversion to give homoallylic alcohols with allyltrimethylsilane employing 10 mol% of titanium tetrafluoride as a Lewis acid in the presence of 10 mol% of L-prolinol in CH3CN/CH2Cl2 (8:2) for 2 h at room temperature. The presence of functionalities such as chloro, nitro and bromo is well tolerated in the presence of catalyst. The reaction proved to be of general nature...

Racemic and enantiomerically pure �-amino-�-trifluoromethyl alcohols were obtained via sequential nucleophilic trifluoromethylation of selected �-imino ketones, derived from arylglyoxals, and subsequent removal of the MeO or Ph(Me)CH substituent, respectively, located at the N-atom. The obtained products, containing a primary amino group, were used for the synthesis of imidazole N-oxides bearin...

Lithium amidoborane (LiNH(2)BH(3), LiAB for short), is capable of chemoselectively reducing α,β-unsaturated ketones to the corresponding allylic alcohols at ambient temperature. A mechanistic study shows that the reduction is via a double hydrogen transfer process. The protic H(N) and hydridic H(B) in amidoborane add to the O and C sites of the carbonyl group, respectively.

Reactions of 2-amino-aryl alcohols with beta-ketoesters catalyzed by a catalytic amount of FeCl3 via tandem benzylation-cyclization produce the corresponding 3-quinolinecarboxylic esters in good to high yields. Extending this methodology to propargylation-cyclization, 2-nitrophenyl propargyl alcohols with beta-ketoesters catalyzed by FeCl3 and SnCl2 also produce the 4-alkyne-3-quinolinecarboxyl...
