Mapping of amide, amine, and aliphatic peaks in the CEST spectra of murine xenografts at 7 T. Magn Reson Med. 2014; 71(5):1841-1853. [PubMed: 23801344]Desmond KL, Moosvi F, Stanisz GJ. Mapping of amide, amine, and aliphatic peaks in the CEST spectra of murine xenografts at 7 T. ...
This disconnection, comparable to a typical amidation, will allow the application of vast existing amine libraries. The reaction is tolerant to a wide range of polar functionalities and is suitable for array formats. Ten oxetane analogues of bioactive benzamides and marketed drugs are prepared. ...
The important bands of the IR spectra of methyl ester of the fatty acids, diethanol amide of the fatty acids and poly(ester amide) of vegetable oil are shown in Table 5.1. As in vegetable oil-based polyester, in the NMR spectrum, similar peaks are obtained. The peaks at δ = 0.8–0.9...
2d). A weaker 15N peak is also detected in the 15N CP MAS spectrum of both PATCnC and CAF-2, and is assigned to an amine nitrogen, suggesting that there are unreacted amine groups still present in the devitrified material; it is difficult to determine whether these are free diamine ...
A solution of propargylamine (1.38 mL, 20.0 mmol) and TRIAZIMOCH (15 wt % H2O, 6.50 g, 20.0 mmol) in THF (100 mL) was added to a solution of L-(+)-lactic acid (3.2 g, 20.0 mmol) at room temperature. The resulting solution was stirred at room temperature overnight. White ...
(<4.3 s), a solution of amine16in solvent B was then introduced into the second mixer with a syringe pump. The reaction was quenched by pouring the mixture into a saturated aqueous solution of NH4Cl, brine and ethyl acetate (micro-flow reactor setup, seeSupplementary Methods). To ...
Main peak of infrared absorption spectra (IR) 3310, 3080, 2940, 2860, 1730, 1645, 1550, 1470, 1415, 1270, 1120, 1030, 950, 880, 735 cm-1 EXAMPLES 2 THROUGH 6 Five types of polyester amides each having a compositional ratio by weight of polybutylene terephthalate to polydodecaneamide as...
due to their abundant availability from natural sources and the potential biodegradability of their derivatives under certain enzymatic catalyzed conditions, have often been chosen as the source for the amine group of the biodegradable poly(ester-amide)s. It has also been reported that the inclusion ...
Infrared (IR) spectra are recorded on a Perkin-Elmer® 681 spectrophotometer. Nuclear magnetic resonance (NMR) spectra are obtained on a Varian® VXR-200 spectrometer using tetramethylsilane as internal standard. Elemental analyses are obtained using a Control Equipment Model 240XA Elemental Analyzer...
