A simple and nontoxic fluorescent chemosensor of di-O-methyl curcumin has been prepared from curcumin. The sensor exhibited selective and sensitive fluorescent responses toward A13+ over a wide range of metal ions, s...
Treatment of enol ether or thiol enol ether of phenylethanals with sulfuric or polyphosphoric acid in toluene or xylene gave 2-phenylnaphthalene in good yield. More importantly, a one-pot reaction has been developed.
The aldol reaction of the silyl enol ether of cyclopent-2-enone with aldehydes is mediated by various Lewis acids.Threo isomers are the major diastereoisomers formed in most cases.A reverse diastereoselectivity was ob...
