PDF-ALDOL ORGANIC SYNTHESIS ALDOL CONDENSATION REACTION TE

Th is makes the aldol reaction an important reaction for organic synthesis Origina lly the al dol reaction used ethanal see below and the refore the product contained both an ald ehyde and an alcoh ol functional group thus it became known as the al. But reaction can be engineered to force aldol product Enolate can be formed transiently as above or uantitativel e w LDA an unsaturated ketone qy In base alone reaction stops at alcohol In base and heat aldol is dehydrated loses H O The Aldol Co Induced.
