Synthesis of Nitriles from Aldoximes and Primary Amides Using XtalFluor-E
Keita, Massaba,Vandamme, Mathilde,Paquin, Jean-Fran?ois
, p. 3758 - 3766 (2015/11/28)
The dehydration reaction of aldoximes and amides for the synthesis of nitriles using [Et2NSF2]BF4 (XtalFluor-E) is described. Overall, the reaction proceeds rapidly (normally 1 h) at room temperature in an environmentally benign solvent (EtOAc) with only a slight excess of the dehydrating agent (1.1 equiv). A broad scope of nitriles can be prepared, including chiral nonracemic ones. In addition, in a number of cases, further purification of the nitrile after the workup was not required.
Anthranilimide-based glycogen phosphorylase inhibitors for the treatment of Type 2 diabetes: 2. Optimization of serine and threonine ether amino acid residues
Sparks, Steven M.,Banker, Pierette,Bickett, David M.,Clancy, Daphne C.,Dickerson, Scott H.,Garrido, Dulce M.,Golden, Pamela L.,Peat, Andrew J.,Sheckler, Lauren R.,Tavares, Francis X.,Thomson, Stephen A.,Weiel, James E.
scheme or table, p. 981 - 985 (2009/08/15)
Optimization of the amino acid residue of a series of anthranilimide-based glycogen phosphorylase inhibitors is described leading to the identification of serine and threonine ether analogs. t-Butylthreonine analog 20 displayed potent in vitro inhibition of GPa, low potential for P450 inhibition, and excellent pharmacokinetic properties.
Novel jadomycins: Incorporation of non-natural and natural amino acids
Jakeman, David L.,Farrell, Spring,Young, Wendy,Doucet, Rene J.,Timmons, Shannon C.
, p. 1447 - 1449 (2007/10/03)
Electrospray ionization mass spectrometry of extracts from Streptomyces venezuelae ISP5230 cultures grown on chemically synthesized non-natural l-amino acids, d-amino acids or any of the 20 natural amino acids demonstrated incorporation of the amino acid into a jadomycin B analogue.
Studies on 2-Aziridinecarboxylic Acid. VI. Synthesis of β-Alkoxy-α-Amino Acids via Ring-opening Reaction of Aziridine
Nakajima, Kiichiro,Neya, Masahiro,Yamada, Shinichi,Okawa, Kenji
, p. 3049 - 3050 (2007/10/02)
The reaction of aziridine derivatives having a urethane-type protecting group with several alcohols in the presence of boron trifluoride etherate afford the corresponding optically pure O-alkylserine and O-alkylthreonine derivatives via a ring-opening reaction of aziridine in good yield.
