Mori, K.: Synthetic chemistry of insect pheromones and juvenile hormones - Recent developments in the chemistry of natural carbon compounds 9. (Budapest, 1979)

RECENT DEVELOPMENTS IN THE CHEMISTRY OF NATURAL CARBON COMPOUNDS Volume 9 The 9th volume of the series comprises three independent parts being of interest to organic chemists, biochemists, phyto­chemists and biologists. The synthesis of insect phero­mones and juvenile hormones, commanding an ever increasing interest, is reported in great detail by K. Mori. His presen­tation includes a large number of synthetic schemes and equa­tions utilizing all the achieve­ments of modern organic chem­istry. The review by B. Stoianova- Ivanova deals with changes in the composition of Bulgarian rose flower processed by extrac­tive methods as compared with the older technique of steam distillation. Both products, i. e. rose wax and absolute, have been analyzed in detail for saturated and unsaturated aliphatic hy­drocarbons, fatty acids, alcohols, ketones, diols, etc., leading to conclusions on the biosynthesis of plant waxes. Chalcone epoxides, deemed to be important intermediates in the biosynthesis of flavonoids are reported by Gy. Litkei. In­vestigations on the Algar- Flynn-Oyamada reaction are separately discussed, and a new mechanism, revising older ones, is forwarded for its interpreta­tion.
