β-Nitroalcohols can be efficiently obtained with the help of Amberlyst A-21, as heterogeneous basic catalyst, with or without solvent. This method is far superior to the heterogeneous catalysts previously reported for the nitroaldol (Henry) reaction, in f
Stereochemical control in microbial reduction. 12. (S)-4-nitro-2-butanol as a source to synthesize natural products

(S)-(+)-4-Nitro-2-butanol (1) obtained by the stereoselective reduction of 4-nitro-2-butanone by bakers' yeast was employed for the syntheses of natural products. A precursor of (+)-brefeldin A is synthesized starting from this chiral building block by 10 steps short-cut procedure compared with the shortest method so far reported. (S)-(+)-Sulcatol is obtained in much better enantiomeric purity than those reported. The reactivity of 1 in base-catalyzed condensations with Michael acceptors or aldehydes is largely affected by a base employed as the catalyst.
