<strong>SYNTHESIS OF FRAGRANCES STARTING FROM </strong><strong>CYCLIC VINYL </strong><strong>KETONES</strong>

Abstract

Cyclic vinyl ketones (Figure 1) are potential precursors for the synthesis of esters ( Figure 2) or lactones (Figure 3), which can be used as a fragrance in the cosmetic industry, in the manufacture of soaps, detergents etc. The first step of the synthesis starting from vinyl ketones is addition of hydrogen cyanide to activated double carbon-carbon bond in the cyclic vinyl ketones.
