Trifluoroethanol Promoted Castagnoli–Cushman Cycloadditions of Imines with Homophthalic Anhydride
Molecules, 2022 Lactams are essential compounds in medicinal chemistry and key intermediates in the synthesis of natural products. The Castagnoli–Cushman reaction (CCR) of homophthalic anhydride with imines is an exciting method for accessing cyclic densely substituted ...

Imine-Enamine Tautomerism -Nucleophilic Reactions of Imines [PDF]
Zeitschrift für Naturforschung B, 1982 Abstract A reinvestigation of the reactivity of N-isopropylidene cyclohexylamine to methyl acrylate by GC-MS analysis has shown that the major product is the β-aminoester (9) formed by the N-alkylation of cyclohexylamine which may be generated by a dimerisation-elimination sequence.

Cobalt Catalyzed Enantioselective Reductive Coupling of Imines and Internal Alkynes
, 2023 Chiral allylic amines hold significant importance as structural components in natural products, pharmaceuticals, and chiral catalysts. In this study, we have delved into cobalt-catalyzed enantioselective reductive coupling of imines with internal alkynes.

Experimental and Theoretical Studies on the Reactions of Aliphatic Imines with Isocyanates
, 2023 In the context of a project aiming at the replacement of the 3-substituted β-lactam ring in classical β-lactam antibiotics by an N(3)-acyl-1,3-diazetidinone moiety, we have investigated the reaction of isocyanates with imines derived from allyl glycinate

Direct Iminization of PEEK [PDF]
Macromolecules, 2011 Semi-crystalline poly(ether ketone)s are important high-temperature engineering thermoplastics, but are difficult to characterize at the molecular level because of their insolubility in conventional organic solvents. Here we report that polymers of this type, including PEEK, react cleanly at high temperatures with low-volatility aralkyl amines to ...
