Rhodium-catalyzed [2+2+2] cycloaddition of oximes and diynes to give pyridines.
نویسندگان
چکیده
Oximes and diynes undergo efficient cycloaddition in the presence of a catalytic amount of a cationic rhodium(I)/dppf complex (see scheme). Spontaneous dehydration of the initially formed cycloadducts leads to the formation of a variety of substituted pyridines in moderate to good yields. The transformation could also be achieved in a one-pot procedure using aldehydes.

Synthesis of non-proteinogenic phenylalanine derivatives by rhodium-catalyzed [2+2+2] cycloaddition reactions.
Non-proteinogenic phenylalanine derivatives were efficiently prepared by Rh(I)-catalyzed [2+2+2] cycloaddition reactions between enantiopure and racemic propargylglycine amino acids, with different protective groups, and diynes. Diverse substituents, including tags such as dansyl or dabsyl, were introduced onto the aromatic ring of the amino acid derivatives by selecting the most appropriate di...

The de novo synthesis of pyridines from smaller molecules has attracted a lot of interest since pyridine is one of the most important heterocyclic structural motifs in numerous areas of organic chemistry. Many developed syntheses, such as the Kr hnke or the Hantzsch reaction, rely on condensation reactions of smaller molecules, but a number of synthetic approaches including cycloaddition reacti...
