Abstract:

A series of N-phenethylcinnamamides were subjected to the Bischler–Napieralski reaction to furnish diverse 1-styryl-3,4-dihydroisoquinolines. We noticed that the desired products were unstable when the reaction was performed under conventional solvent conditions. However, when [bmim]PF6 was used as the reaction media, the nature of the Bischler–Napieralski reaction promoted an unusual in situ ionic interchange between this ionic liquid and the dihydroisoquinoline core that led to the stabilization of the desired 1-styryl-3,4-dihydroisoquinolines, allowing their isolation as hexafluorophosphate

Abstract:

AbstractThe iridium (III) complex of pentamethylcyclopentadiene and (S,S) or (R,R)-1,2-diphenyl-N′-tosylethane-1,2-diamine is an effective catalyst for the asymmetric transfer hydrogenation of imines under acidic conditions. However, the enantiomeric excess (ee) of the product amines from the reduction of 1-methyl-3,4-dihydroisoquinolines in either acetonitrile or dichloromethane, decreases exponentially. The dominant cause of the enantioselectivity is the difference in kinetic order of the formation of the two enantiomers with the S-enantiomer being formed in a first-order process whereas tha

Abstract:

Many isoquinoline alkaloids are biologically active compounds and successfully used as pharmaceuticals. Compounds belonging to the isoquinolines and tetrahydroisoquinolines (TIQs) can be used as anesthetics, antihypertensive drugs, antiviral agents, and vasodilators. In the presented studies, the search for new compounds and synthesis of tetrahydroisoquinoline alkaloid derivatives was undertaken. Several dihydroisoquinolines were synthesized by Bishler–Napieralski reaction from the corresponding amides. Dihydroisoquinolines were reduced with sodium borohydride to obtain racemic tetrahydroisoqu

Abstract:

Starting from the chiral 5,6,7,8-tetrahydroquinolin-8-ol core, a series of amino-phosphorus-based ligands was realized. The so-obtained amino-phosphine ligand (L1), amino-phosphinite (L2) and amino-phosphite (L3) were evaluated in iridium complexes together with the heterobiaryl diphosphines tetraMe-BITIOP (L4), Diophep (L5) and L6 and L7 ligands, characterized by mixed chirality. Their catalytic performance in the asymmetric hydrogenation (AH) of the model substrate 6,7-dimethoxy-1-phenyl-3,4-dihydroisoquinoline 1a led us to identify Ir-L4 and Ir-L5 catalysts as the most effective.

Followed by an intramolecular dehydration of the 3a-i with the modified Mitsunobu’s reaction, the target flavanones (I-4a-i) were obtained. Moreover, the reaction of I-1 and I-2 at the same conditions but at reflux gave flavanones in one pot with good yields.
