Asymmetric Synthesis of N-Fmoc-(S)-7-aza-tryptophan via Alkylation of Chiral Nucleophilic Glycine Equivalent
Zou, Yupiao; Takeda, Ryosuke; Han, Jianlin ; Konno, Hiroyuki; Moriwaki, Hiroki; Abe, Hidenori; Izawa, Kunisuke; Soloshonok, Vadym Anatolievch (Wiley, 2021-06-07)Ni(II)-complexes, derived from glycine Schiff bases with chiral tridentate ligands, have been used as powerful tools for the synthesis of structurally diverse tailor-made amino acids. In this manuscript, asymmetric alkylation ... -
Synthesis and stereochemical assignments of diastereomeric Ni(II) complexes of glycine Schiff base with (R)-2-(N-{2-[N-alkyl-N-(1-phenylethyl)-amino]acetyl}amino) benzophenone; a case of configurationally stable stereogenic nitrogen
Moriwaki, Hiroki; Resch, Daniel; Li, Hengguang; Ojima, Iwao; Takeda, Ryosuke; Aceña Bonilla, José Luis; Soloshonok, Vadym Anatolievch (Beilstein Institut, 2014-02-19)A family of chiral ligands derived from alpha-phenylethylamine and 2-aminobenzophenone were prepared by alkylation of the nitrogen atom. Upon reaction with glycine and a Ni(II) salt, these ligands were transformed into ...
