The two enantiomers of the floral odorant Florhydral(R) were prepared by enzymatic methods, and their olfactory properties were evaluated. (+)-Florhydral(R) was found to be Much more powerful than the (-)-enantionier. (C) 2002 Elsevier Science Ltd. All rights reserved.
A New Enantioselective Catalytic Route to Florhydral<sup>®</sup>
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.
