Enantioselective Michael reactions. Diastereoselective reactions of chlorotitanium enolates of chiral N-acyloxazolidinones with representative electrophilic olefins
摘要:
In the present study we wish to report the details of the diastereoselective reactions of titanium enolates derived from N-propionyloxazolidone 1 in inter-and intramolecular Michael reactions with ethyl vinyl ketone, methyl acrylate, and acrylonitrile (eq 1).
