General Synthesis of 2-, 3-, and 4-Hydroxyalkylphosphonium Salts by the Reaction of Triphenylphosphine with Cyclic Ethers in the Presence of Strong Acids.

Cyclic ethers were efficiently converted to the corresponding hydroxyalkylphosphonium salts by the reaction with triphenylphosphine and trifluoromethanesulfonic or trifluoroacetic acid.The reaction of these salts with bases afforded the corresponding phos

Application of sulfuryl chloride for the quick construction of β-chlorotetrahydrofuran derivatives from homoallylic alcohols under mild conditions

An efficient and mild method is reported for the construction of β-chlorotetrahydrofuran derivatives by 5-endo chlorocycloetherification of homoallylic alcohols. The system employs sulfuryl chloride as the chlorinating agent under catalyst-free conditions. A variety of homoallylic alcohols with aryl or alkyl substituents were smoothly converted into β- chlorotetrahydrofurans in yields up to 98%.

One-pot synthesis of fused benzo[c]carbazoles by photochemical intramolecular annulation of 3-acyl-2-haloindoles with tethered styrenes

An efficient procedure for the synthesis of fused benzo[c]carbazoles has been achieved in moderate to high yields by the one-pot photochemical annulation of 3-acyl-2-haloindoles with tethered styrenes by photoinduced electron-transfer coupling, electrocyclic reactions, and deacylative aromatization in the presence of pyridine. Fused furo[2,3-c]carbazoles were also synthesized under the same conditions. 5,6-Dihydrobenzo[c]pyrrolo[1,2,3-lm] carbazoles were oxidized by DDQ to afford aromatic benzo[c]pyrrolo[1,2,3-lm] carbazole products in moderate to high yields.
