Mandelic acid catalyzed one-pot three-component synthesis of α-aminonitriles and α-aminophosphonates under solvent-free conditions at room temperature

A simple, mild, straightforward, efficient and eco-friendly protocol has been developed for the synthesis of a series of α-aminonitriles via the one-pot three-component Strecker reactions between various aldehydes, amines and trimethylsilyl cyanide using a catalytic amount of mandelic acid as a naturally occurring, low-cost, efficient organo-catalyst under solvent-free conditions at room temperature. Under the same optimized conditions synthesis of α-aminophosphonates were also achieved via the one-pot three-component Kabachnik-Fields reactions of aldehydes, amines and triethyl phosphate.

Synthesis of α-Aminonitriles and 5-Substituted 1H-Tetrazoles Using an Efficient Nanocatalyst of Fe3O4@SiO2–APTES-supported Trifluoroacetic Acid

Fe3O4@SiO2–APTES-supported trifluoroacetic acid nanocatalyst was used for the one-pot synthesis of α-aminonitriles via a three-component reaction of aldehydes (or ketones), amines, and sodium cyanide. This method produced a high yield of 75–96% using only a small amount of the catalyst (0.05?g) in EtOH at room temperature. The catalyst was also employed for the synthesis of 5-substituted 1H-tetrazoles from nitriles and sodium azide in EtOH at 80°C. The tetrazoles were produced with good-to-excellent yields in a short reaction time of 4?h. Both synthetic methods were carried out in the absence of an organic volatile solvent. Because the supported trifluoroacetic acid generated a solid acid on the surface, thus the acid corrosiveness was not a serious challenge. This heterogeneous nanocatalyst was magnetically recovered and reused several times without significant loss of catalytic activity.

Trityl Isocyanide as a Mechanistic Probe in Multicomponent Chemistry: Walking the Line between Ugi- and Strecker-type Reactions

Herein, we describe the versatile application of triphenylmethyl (trityl) isocyanide in multicomponent chemistry. This reagent can be employed as a cyanide source in the Strecker reaction and as convertible isocyanide in the preparation of N-acyl amino acids by Ugi 4CR/detritylation and free imidazo[1,2-a]pyridin-3-amines by a Groebke-Blackburn-Bienaymé 3CR condensation/deprotection protocol. The mechanisms of these three classical MCRs intersect at the common N-trityl nitrilium ion intermediate, whose predictable reactivity can be exploited towards chemoselective transformations. Fate of the nitrilium ion: The application of trityl isocyanide as a mechanistic tool to dissect different reaction pathways in multicomponent chemistry is described. This reagent can be employed as a cyanide source in the Strecker reaction and as a convertible isocyanide in the preparation of N-acyl amino acids by Ugi 4CR/detritylation and free imidazo[1,2-a]pyridin-3-amines by Groebke-Blackburn-Bienaymé 3CR condensation/deprotection. Chemoselective transformations were achieved by the rational choice of reaction conditions.
