Dimethylamination of Primary Alcohols Using a Homogeneous Iridium Catalyst: A Synthetic Method for N, N-Dimethylamine Derivatives
Jeong, Jaeyoung,Fujita, Ken-Ichi
, p. 4053 - 4060 (2021/03/09)
A new catalytic system for N,N-dimethylamination of primary alcohols using aqueous dimethylamine in the absence of additional organic solvents has been developed. The reaction proceeds via borrowing hydrogen processes, which are atom-efficient and environmentally benign. An iridium catalyst bearing an N-heterocyclic carbene (NHC) ligand exhibited high performance, without showing any deactivation under aqueous conditions. In addition, valuable N,N-dimethylamine derivatives, including biologically active and pharmaceutical molecules, were synthesized. The practical application of this methodology was demonstrated by a gram-scale reaction.

Water-soluble phosphinothiol reagents
-
, (2013/04/13)
Water soluble reagents and methods for the formation of an amide bond between a phosphinothioester and an azide in an aqueous medium. The phosphinothioester is generated using a water-soluble phosphinothiol reagent. This reaction allows formation of an amide bond between a wide variety of chemical species including amino acids, peptides or protein fragments in an aqueous solution. Of particular interest, this reaction allows for the formation of an amide bond in a physiological setting. In a specific embodiment, this invention provides reagents and methods for peptide ligation in an aqueous medium. The reaction eliminates the need for a cysteine residue and is traceless leaving no residual atoms in the ligated peptide product.

Sowa, Sylwia,Mühlberg, Michaela,Pietrusiewicz, K. Michal,Hackenberger, Christian P.R.
, p. 3465 - 3472 (2013/07/11)
In this paper, we demonstrate the applicability of water-soluble p-dimethylaminoethyl substituted phosphinomethanethiol in acetyl transfer reactions by the traceless Staudinger ligation with unprotected *-azido lysine containing peptides in aqueous buffer systems. Additionally, we present an improved synthesis pathway for the water-soluble phosphinothiol linkers requiring less steps in a comparable overall yield in comparison to previously published protocols.

Page/Page column 38, (2010/03/02)
An objective of the present invention is to provide compounds of formula (1) or their pharmacologically acceptable salts or solvates wherein A represents aryl; R1 represents N-optionally substituted C1-6 alkyl-N-optionally substituted C1-6 alkylamino-C1-6 alkyl; R2 represents a hydrogen atom or optionally substituted C1-6 alkyl; R3 represents optionally substituted C1-6alkyl or C3-6 cycloalkyl-C1-4 alkyl; m is 1 to 3; n is 0; and p is 0 to 2. The compounds are novel lincomycin derivatives that have a potent activity against resistant Streptococcus pneumoniae, which have recently posed problems, in the treatment of infectious diseases. Further, the compounds are usable as antimicrobial agents and are useful for preventing or treating bacterial infectious diseases.
Structure-activity correlations for β-phenethylamines at human trace amine receptor 1
Lewin, Anita H.,Navarro, Hernan A.,Wayne Mascarella
, p. 7415 - 7423 (2008/12/22)
A cell line in which RD-HGA16 cells were stably transfected with the hTAAR 1 receptor was created and utilized to carry out a systematic evaluation of a series of β-phenethylamines. Fair agreement was observed with data obtained for aryl and ethylene chain substituted analogs in an AV12-664 cell line in which hemagglutinin-tagged hTAAR 1 was stably co-expressed with rat Gαs. Analogs with multiple substituents as well as analogs with bulky groups were found to be partial agonists. Analogs in which the primary amino group was converted to a secondary or a tertiary amino group by N-methylation were also partial agonists. Comparative Molecular Field Analysis (CoMFA) using the potency data yielded a regression coefficient r2 of 0.824. The steric field contribution to the model was 61% with the balance (39%) contributed by the electrostatic field. The collective results suggest that increasing steric bulk both at the amino nitrogen, particularly by N-dimethylation, and at the 4-position of the aromatic ring leads to low efficacy ligands.
