Flavors, Fragrances, and Food Additives from Cresol Derivatives 

Since the dawn of civilization, say, 5000 years ago perfumes and perfumery chemicals encompassing flavors and fragrances and even pleasant food additives attracted attention in India and were used in temples, religious rites and even for personal sophistication. The earliest reference to such materials was to he found in the Vedas, say, during 2000-2500 BC. In particular, sandalwood, camphor, saffron, etc. were mentioned in connection with certain rites. 

Perfume takes its name from the Latin word perfumare (to fill with smoke), since in its original form it was incense burned in Egyptian temples. Similarly China was a pioneering country in the field of flavors and fragrances since they were known to the Chinese some 3000 years ago. These were all natural products and perhaps they became popular in Europe at a later date. It is only during the last few decades that synthetic perfumery products (flavors, fragrances, and 151

Two synthetic bridged nitrogen heterocycles are also prepared on a commercial scale. The pentazocine synthesis consists of a reductive alkylation of a pyridinium ring, a remarkable and puzzling addition to the most hindered position, hydrogenation of an enamine, and acid-catalyzed substitution of a phenol derivative. The synthesis is an application of the reactivity rules discussed in the alkaloid section. The same applies for clidinium bromide.

All clinically used opiates have the same pharmacology since they all act on the mu receptor with the exception of the kappa agonist, pentazocine. Opiates are used to relieve moderate to severe pain whatever the cause (accidents, post-operative pain, cancer, etc.) and are used pre-, intra- and post-operatively. The mu opiates differ only in potency and pharmacokinetics. Examples are ...
