MnO2/TiO2 catalyzed synthesis of coenzyme pyridoxamine-5′-phosphate analogues: 3-deoxypyridoxamine-5′-phosphate

The highly efficient-selective synthetic route of the pyridoxal-5′-phosphate (vitamin B6, PLP) analogues: C3 substituted deoxy derivatives of pyridoxal (PL), pyridoxal-N-oxide (PLNO), pyridoxamine (PM), pyridoxamine-5′-phosphate (PMP) and pyridoxal-5′-phosphate (PLP), were developed via reduction and followed by selective oxidation in one pot using solid supported nanoparticles. The salient features of this strategy are: economic two-fold conversion, more Lewis acid sites, vacancies on the nanoparticle surfaces, and good yields of 3-deoxypyridoxal and 3-deoxypyridoxamine-5′-phosphate.

Cobalt-catalyzed alkyne-nitrile cyclotrimerization to form pyridines in aqueous solution.

A new, water-soluble cobalt(I) catalyst has been used in the aqueous, chemospecific, cyclotrimerization of one nitrile with two alkynes for the synthesis of highly functionalized pyridines. Several different functional groups are well incorporated in this
