Lewis acid mediated 5/6/7-endo-dig hydroalkoxylation-reduction cascade on internal alkynols gave an expedient, stereoselective synthesis of cyclic ethers and 1,4-oxazepanes. The strategy has been extended to the first examples of hydroalkoxylation-alkyne

In the presence of a catalytic amount of triphenylmethylium hexachloroantimonate or a catalyst system of antimony pentachloride, chlorotrimethylsilane and tin(II)iodide, α-substituted cyclic ethers are stereoselectively prepared from lactones by successiv
SUBSTITUTION REACTIONS OF 2-BENZENESULPHONYL CYCLIC ETHERS WITH CARBON NUCLEOPHILES
Brown, Dearg S.,Bruno, Maurizio,Davenport, Raymond J.,Ley, Steven V.
, p. 4293 - 4308 (2007/10/02)
Direct substitution of 2-benzenesulphonylcyclic ethers was studied using a variety of carbon nucleophiles.These nucleophiles included organozinc reagents (derived from aryl, vinyl and alkynyl Grignard reagents) or silyl enol ethers, silyl ketene acetals,
SUBSTITUTION REACTIONS OF 2-BENZENESULPHONYL CYCLIC ETHERS WITH SILYL ENOL ETHERS PROMOTED BY ALUMINIUM TRICHLORIDE
Brown, Dearg S.,Ley, Steven V.,Bruno, Maurizio
, p. 773 - 777 (2007/10/02)
Several cyclic ether 2-benzenesulphones were shown to react with silyl enol ethers in the presence of AlCl3 to give the corresponding alkylated products in good yield.Where substitution occured to give 2,6-disubstituted products there was a marked prefere
A CONVENIENT SYNTHESIS OF CYCLIC ETHERS FROM SILOXY CARBONYL COMPOUNDS
Homma, Koichi,Mukaiyama, Teruaki
, p. 259 - 262 (2007/10/02)
Five-seven membered cyclic ethers are prepared by one-pot procedure in good yields from γ-, δ-, and ε-siloxy carbonyl compounds, respectively, on treatment with silyl nucleophiles (triethylsilane, allyltrimethylsilane, trimethylsilyl cyanide, etc.) in the
