Sharma, Pankaj published the artcileEffect of sulfamic acid on 1,3-dipolar cycloaddition reaction: mechanistic studies and synthesis of 4-aryl-NH-1,2,3-triazoles from nitroolefins, Recommanded Product: 1,2-Dimethoxy-4-(2-nitrovinyl)benzene, the publication is Journal of the Brazilian Chemical Society (2017), 28(4), 589-597, database is CAplus.
A facile and new metal-free 1,3-dipolar cycloaddition reaction for the synthesis of 4-aryl-NH-1,2,3-triazoles, e.g., I from nitroolefins, e.g., 3-nitro-2-phenyl-2H-1-benzopyran and NaN3 employing NH2SO3H has been developed. Sulfamic acid proved to be an efficient additive in this transformation by inhibiting the formation of triaryl benzene. Mechanistic aspects and key intermediates associated with this transformation have also been characterized by online monitoring of the reaction using electrospray ionization tandem mass spectrometry method (ESI-MS/MS). The protocol emphasizes broad substrate scope for many functionalities, simple reaction conditions such as stability to open air, less reaction time, easy work-up, eco-friendly and with good to excellent yields.
