Alpaslan, Gokhan; Ozdamar, Ozgur; Odabaşoğlu, Mustafa; Büyükgüngör, Orhan; Erdonmez, Ahmet (Int Union Crystallography, 2006)The title compound, C14H17ClN2O3, adopts a keto-hydrazo tautomeric form stabilized by an intramolecular N-H center dot center dot center dot O hydrogen bond. The molecule is roughly planar. -
Proline-beta(3)-Amino-Ester Dipeptides as Efficient Catalysts for Enantioselective Direct Aldol Reaction in Aqueous Medium
De Nisco, Mauro; Pedatella, Silvana; Ullah, Hidayat; Zaidi, Javid H.; Naviglio, Daniele; Ozdamar, Ozgur; Caputo, Romualdo (Amer Chemical Soc, 2009)Dipeptides obtained from L-proline and beta(3)-L-amino acids are reported to catalyze enantioselective direct aldol reaction in aqueous medium, leading to significant anti: syn diastereomeric ratios and enantiomeric excesses. ... -
