The third symposium organized jointly by the British Society of Perfumers and the Society of Cosmetic Chemists of Great Britain on “The Future of Perfumery?” was held April 4-6, 1977, at the Stratford-upon-Avon Hilton Hotel. This was their most successful venture yet and attracted a record attendance for both organizations. Almost 280 delegates attended from France, Germany, Switzerland, the Netherlands, Denmark, Sweden, Bulgaria, Japan, the United States, and Canada as well as the host country, Great Britain. During the two days of sessions the lecture program reviewed past influences and present trends. From these, forecasts were made of possible future developments and of obstacles that may inhibit continuing progress. Titles and synopses (where available) follow.
Alkyl substituted 3-methylcyclohex-2-en-1-ones, B. A. McAndrew. The versatility of Hagemann’s Ester (ethyl 2-methyl-4-oxocyclohex-2-ene-1-carboxylate) as an intermediate in the synthesis of a range of alkylated 3-methylcyclohex-2-en-1-ones has. been demonstrated. The effects of the substitution pattern and of the chain length of the alkyl substituent on the odor of these ketones was discussed and some comparisons drawn with their cyclopentenone analogies (dihydrojasmones).
