The Claisen Transposition in the Preparation of New Odorant Substances

Through this work we have verified that the application of this reaction to different ketones produce γ,δ-unsaturated ketones with a wide range of interesting notes. We believe that it is a good reaction to use in the search for new odorant substances.

Rational Odorant Design: Fantasy or Feasibility?

Exploring the two approaches to rational odor design and the possibilities of each. Why do we strive for rational design of odorants? Since the birth of synthetic organic chemistry in the mid-19th century, fragrance chemists have sought to design and produce fragrance ingredients to supplement those obtained from plant (and formerly animal) sources.

Progress in Essential Oils: Sweet Fennel Oil and Extract

In this column, Brian M. Lawrence reviews the composition of sweet fennel oil and extract as found by various researchers. For example, a commercial sample of sweet fennel oil was screened for its anti-platelet activity by Tognolini et al. (2006) and Guerini et al. (2006) using GC-FID and GC/MS. Results are reported herein.

Vanilla flavor is dominated by phenols and their transformation products mostly derived from enzymatic hydrolysis of the phenyl-β-D-glucosides. Cocoa bean flavor is dominated by Strecker aldehydes and pyrazines and other products generated during the roasting process of the beans.
