A biomimetic total synthesis of (±)-rossinone B (I) has been achieved through a highly efficient strategy featuring a series of rationally designed reactions, including a one-pot allylic rearrangement/oxidation reaction to generate the vinyl quinone II, an intramol. vinyl quinone Diels-Alder reaction to construct the linear 6-6-5 tricyclic core of III, and a double conjugate addition/β-elimination cascade to complete the total synthesis of I. This study involved multiple reactions and reactants, such as (2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5Related Products of 37905-02-5).
(2E,6E)-3,7-Dimethyl-8-oxoocta-2,6-dien-1-yl acetate (cas: 37905-02-5) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Related Products of 37905-02-5
