Adding to the confusion! Synthesis and metalation of pyrazole analogues of the porphyrins

N-substituted pyrazole dialdehydes are shown to react with a tripyrrane under '3 + 1' conditions to give aza-analogues of the N-confused porphyrins; these novel porphyrinoids show borderline aromatic properties and readily afford organometallic derivatives with Ni(OAc)2 and Pd(OAc)2.

Preparative scale conversion of D-xylose into hydrophilically functionalized pyrazoles

An expeditious, 4-step procedure is described for the conversion of bulk-scale accessible D-xylose into 5-hydroxymethyl-1-phenylpyrazole-3-carboxaldehyde (3), which, in turn, is converted into various pyrazole building blocks with versatile application profiles, such as the l-phenylpyrazole-3,5-dicarboxylic acid (9), the respective 3,5-dialdehyde (10), and 3,5-bis(aminomethyl)-l-phenylpyrazole(13).
