What is Oxidation of Aldehydes to α,β-Unsaturated Aldehydes via α-Chloroaldimines about?
The oxidation of aldehydes to a@-unsaturated aldehydes has been performed by a sequence of reactions involving conversion into aldimines, chlorination at the a-position to form a-chloroaldimines, base-induced dehydrochlorination and h drol sis The four-step transformation can be executed without isolation of the intermediates. This metKod xas'been applied to the synthesis of an artificial flavor, i.e. 2-butyl-3phenylpropenal. a,/?-Unsaturated aldehydes are important functionalyzed carbonyl compounds in synthetic organic chemistry. They have a pronounced industrial use as synthetic flavor additive of candies, baked goods, ice-cream and dairy productsio2. In addition, a,/?-unsaturated aldehydes contribute to some extent to the natural flavor of vegetables, e.g. onions'. Branched 2-alkenals are formed during frying or roasting of foods and contribute as such significantly to the flavor characteristics of foodstuffs. Most a,p-unsaturated aldehydes are synthesized via a variety of condensation reactions. There exist relatively few methods for aldehydes and subsequent dehydrohalogenation is not a successful procedure because of competing side reactions in the latter step12. A better meth
