1. ChemInform Abstract: A New Prenylation Method Using the Lithium Enolate of Prenal. Reaction with Polyunsaturated Aldehydes. A Short Access to Retinal

Author

Jacques Poirier, Jérôme Emile Georges Guillemont, Lucette Duhamel, and P. Chabardes

Subjects
chemistry.chemical_compound, Hydrolysis, Prenylation, Chemistry, chemistry.chemical_element, Organic chemistry, Lithium, Retinal, General Medicine, Silyl enol ether, Enol
Abstract

The enolate of prenal 1 prepared from the corresponding silyl enol ether 2 or enol acetate 3 led to a γ-regiospecific reaction with polyunsaturated aldehydes 4 yielding dihydropyrans 5 leading after hydrolysis to polyenals 7 . This process allows the introduction of the isoprenyl skeleton. A synthesis of retinal. from β-ionylidenacetaldehyde is reported.

2. ChemInform Abstract: A New Prenylation Method Using the Lithium Enolate of Prenal. Reaction with Aldehydes and α,β-Unsaturated Aldehydes

Author

Jacques Poirier, Jérôme Emile Georges Guillemont, Lucette Duhamel, and P. Chabardes

Subjects
Hydrolysis, Prenylation, Chemistry, Yield (chemistry), chemistry.chemical_element, Organic chemistry, Lithium, General Medicine, Conjugate
Abstract

A γ-condensation of the enolate of prenal 1 is observed with aldehydes and α,β-unsaturated aldehydes. In this last case, a conjugate addition is obtained. Intermediate dihydropyrans 4 yield dienals 5 by hydrolysis.
