Enantioselective enzymatic desymmetrizations in organic synthesis.

Enantiotopic selective reduction of 1-(benzofuran-2-yl)ethanones 1a – d , 1-(benzofuran-2-yl)-2-hydroxyethanones 4a – c and 2-acetoxy-1-(benzofuran-2-yl)ethanones 3a – c was performed by baker's yeast for preparation of optically active (benzofuran-2-yl)carbinols [( S )- 5a – d , ( S )- 6a – c and ( R )- 6a – c , enantiomeric excess from 55 to 93% ee].

Convenient synthetic route to (+)-faranal and (+)-13-norfaranal : The trail pheromone of pharaoh's ant and its congener 1

A series of 1-acetoxy-3-aryloxypropan-2-ones 1a–m were synthesized and subjected to biotransformation by baker's yeast yielding optically active monoacetates 5 or ent - 5 and/or diols 4 of moderate to excellent enantiomeric purity. The dependence of the reduction/hydrolysis ratio and stereoselectivity on the size and substitution pattern of the aromatic moiety in the substrate is also discussed.

Enantiomer selective hydrolysis of racemic 1,2-diol diacetates (rac-2a-h) was investigated by using the inexpensive commercial porcine pancreatic lipase. The hydrolysis proceeds with variable regioselectivity but with moderate to good enantioselectivity yielding a mixture of isomeric monoacetates (3a-h and 4a-h) and unchanged diacetate enantiomers (2a-h). Evidence was found that both monoacetates (3a-h and 4a-h) are formed with the same sense of enantiomer selectivity.
