Application of an Ugi type reaction to an N-silyl-4,4-disubstituted 1,4-dihydropyridine
2009, TetrahedronCitation Excerpt :For instance 1,2-dihydropyridine derivatives have successfully been employed as key intermediates in the total synthesis of (+)-Leuciduline5 and (+)-Melazocin.6 1,4-Dihydropyridines were successfully used, for example, as intermediates in the synthesis of alkaloids of the ervitsine–ervatamine group.7 So far, for practical reasons, mainly 4-unsubstituted and 4-monosubstituted 1,4-dihydropyridines have been employed as building blocks for the construction of more complex molecules whereas 4,4-disubstituted 1,4-dihydropyridines have rarely been used for this purpose.
Beyond the Ugi reaction: less conventional interactions between isocyanides and iminium species
2009, TetrahedronCitation Excerpt :The reactions are mostly performed in methanol (or in binary solvent systems involving methanol such as MeOH/CH2Cl2), but can also be carried out in toluene,68,70 in water,71 in ionic liquids,72 or even neat.73 Since the first reports were published, various methods of providing the acidic catalysis have been proposed: ammonium chloride,62 tosic acid,74 tosic acid/N-hydroxysuccinimide,75 also some supported acid catalysts such as Montmorillonite K-10,73 cellulose sulfuric acid,76 or silica sulfuric acid.77 It is possible to reduce the reaction times under microwave irradiation.73,78
