The Enol Ether Synthesis of Polyenes
نویسندگان
چکیده
Convenient methods for the preparation of 1-alkoxydienes are reviewed. It is shown that 1-alkoxydienes are very reactive and can be successfully used for the synthesis of polyene compounds. These include some important natural products, such as polyene aldehydes, vitamin A aldehyde, the ethers and esters of vitamin A, f3-ionolidenacetaldehyde, f3-C,9-aldehyde and other related compounds. A convenient method of synthesis of polyene dialdehydes, dicarboxylic acids and their derivatives is described. These compounds can be used for the synthesis of carotenoids.

Silyl Enol Ether Prins Cyclization: Diastereoselective Formation of Substituted Tetrahydropyran-4-ones
A diastereoselective synthesis of cis-2,6-disubstituted tetrahydropyran-4-ones was developed. The key step of this methodology, a silyl enol ether Prins cyclization, was promoted by a condensation reaction between a hydroxy silyl enol ether and an aldehyde to afford substituted tetrahydropyran-4-ones. The cyclization was tolerant of many functional groups, and the modular synthesis of the hydro...

Vinyl triflates can be efficiently converted into the corresponding aryl enol ethers by treatment with a phenol, NaO(t)Bu and a catalyst generated from Pd2dba3 and 2-(di-(t)Bu-phosphino)biphenyl.
متن کاملSynthesis and characterization of novel silyl derivatives of curcumin
Abstract:Turmeric is a member of the ginger family (Zingiberaceae), which is extensively used as a spice, food preservative and colouring material. Curcumin is a main bioactive natural compound derived from the rhizome of this plant. Curcumin can exist in several tautomeric forms, keto and enol. The keto form is more stable than enol form. Silyl ethers have proven to be versatile substrates for...
متن کاملThe total synthesis of gambierol.
This communication describes the total synthesis of the marine polyether toxin, gambierol. This work couples our iterative C-glycoside/enol ether-olefin metathesis strategy to the subunits with a unique olefin metathesis/carbonyl olefination reaction to bring the subunits together.
متن کاملA new method for the synthesis of difluoromethyl enol ethers by O-difluoromethylation of 1,3-diones with ClCF2CO2Et.
A facile, efficient, single-step protocol for the synthesis of difluoromethyl enol ether derivatives by O-difluoromethylation of 1,3-diones via in situ generation of difluorocarbene from ClCF2CO2Et has been developed. The functional group tolerance, scalability of the reaction, and mild reaction conditions make it an attractive protocol for the synthesis of biologically relevant difluoromethyl ...
