Synthesis of the key intermediate of coenzyme Q10

(2′E)-1-(3-methyl-4-p-toluenesulfonyl-2-butene)-6-methyl-2,3,4, 5-tetramethoxybenzene (4) is the key intermediate in the synthesis of coenzyme Q10via a coupling reaction with solanesyl bromide. In this paper, we report a simple and effective synthesis of

Synthesis of (±)- and (-)-botryodiplodin using stereoselective radical cyclizations of acyclic esters and acetals

Three different routes for the stereoselective synthesis of botryodiplodin have been investigated. The intramolecular allylation of acetals proved to be unsatisfactory due to unstable intermediates and poor stereocontrol. Zard intramolecular radical allyl

Intramolecular radical allylation with allylic sulfones a synthesis of (±)-botryodiplodin

Isopropenyl-5-membered-ring acetal or lactone are potential precursors of (±)-botryodiplodin (1). Several pathways, involving 5-exo-trig ring closure onto allylic sulfones, have been investigated. The iodine atom transfer methodology allowed the preparati

Synthesen von Carotinen mit ψ-Endgruppen und (Z)-Konfiguration an terminalen konjugierten Doppelbindungen

Five carotenes bearing (5Z)-ψ-end groups were synthesized and carefully characterized: (5Z)-lycopene (6), (5Z,5'Z)-lycopene (7), (5'Z)-neurosporene (8), (5'Z)-β,ψ-carotene (12), and (5'Z)-εψ-carotene (14).

Process for producing a sulfone derivative of vitamin A alcohol

A process for the preparation of vitamin A and esters thereof from the condensation of a sulfone of 2-methyl-4-hydroxy-but-2-ene and an activated derivative of 3-methyl-5-(2,6,6-trimethyl-cyclohexen-1-yl)penta-2,4-diene including intermediates therein.
