results of this coupling chemistry with those obtained with EDC coupling, the data indicate that, although EDC only showed significant coupling of ADH to the peptide under acidic con-ditions up to a pH of 5.8, DMTMM also allowed the reaction at near-neutral pH of 7.4 in PBS buffer (Fig. S1). Subsequent cross-linking experiments using a set of three

Dmtmm coupling

DMTMM can be isolated and used as coupling reagent independently. 7 In contrast to CDMT, DMTMM does not require pre-activation of the carboxylic acid. The coupling efficiency of DMTMM in SPPS was found to be comparable to PyBOP while racemization could be kept below the detection limit. 8 2009-02-25 · To prove that the novel DMTMM PF 6 1c is as active as DMTMM BF 4 1b in coupling reactions, both salts were employed in the amidation of benzoic acid with pyrrolidine , following a protocol developed by Kamiński et al. 7a In directly comparable reactions, the yields obtained were essentially identical, being 78% with 1b and 79% with 1c.

Our first approach was to try to extend the already estab-lished protocol for CDMT activation of carboxylic acids5 to solid phase. CDMT, previously activated with N-meth-ylmorpholine, was treated with N-Fmoc amino The coupling reagent 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMTMM) has been used for condensation of carboxylic acids with amines.27 Herein, we found that DMTMM can mediate amide bond formation between Cγ of Asp and the amine group of backbone, resulting in the formation of Suc in the peptide KR12, even though the 4- (4,6-Dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMTMM) is a highly effective coupling reagent used for both amide synthesis and for the preparation of esters.

TBTU was very effective, for instance, in key macrocyclization and coupling steps in Alternate Name: DMT‐MM; DMTMM.

DMTMM A Novel Coupling Reagent Propylphosphonic anhydride (T3P ®) is a very efficient, nontoxic coupling reagent especially suited for connecting sterically hindered amino acids. A further advantage is the easy removal of byproducts by extraction of the crude product with water. DMTMM can be isolated and used as coupling reagent independently. 7 In contrast to CDMT, DMTMM does not require pre-activation of the carboxylic acid. The coupling efficiency of DMTMM in SPPS was found to be comparable to PyBOP while racemization could be kept below the detection limit.

This feature is quite unique compared to classic coupling reagents such as N,N′-dicyclohexylcarbodiimide, N,N′-diisopropylcarbodiimide, N-acylimidazoles. DMTMM-based coupling reactions were run in 200 mM MOPS buffer pH 7.0 (200 mM (3 [N-morpholino]propanesulfonic acid, 20 mM sodium acetate, 10 mM EDTA) while EDC-based reactions were run in water. 2.4.

For all the substrates tested DMTMM yields were superior at parity of feed ratio. DMTMM chemistry DMTMM [D2919] Methanol; Procedure. To a solution of 3-phenylpropionic Acid (1.80 g, 12.0 mmol) and 2-phenylethylamine (1.60 g, 13.2 mmol) in MeOH (120 mL) was added DMTMM (3.65 g, 13.2 mmol) and the mixture was stirred at room temperature for 1 hour. The solvent was removed under reduced pressure.
