A new enantioselective catalytic route to Florhydral

The valuable fragrance Florhydral [3-(3-isopropylphenyl)butanal] has been synthesized in almost enantiomerically pure form by a new catalytic route. The key step of the process is the enantioselective hydrogenation of (E)-3-(3-isopropylphenyl)but-2-en-1-ol, which is carried out with asymmetric inductions of up to 97% using an iridium-phosphinooxazoline chiral catalyst.

Biocatalysed synthesis of the enantiomers of the floral odorant Florhydral

The two enantiomers of the floral odorant Florhydral were prepared by enzymatic methods, and their olfactory properties were evaluated. (+)-Florhydral was found to be much more powerful than the (-)-enantiomer.
