Cercosporin-Photocatalyzed [4+1]- and [4+2]-Annulations of Azoalkenes Under Mild Conditions

4-Chloro-7-hydr-oxy-6-methyl-1,7-naphthyridin-8(7H)-one
Abstract:
The title compound, C(9)H(7)ClN(2)O(2), was prepared by reaction of methyl 4-chloro-3-(prop-1-yn-yl)picolinate with hydroxy-l-amine in MeOH/KOH solution. The two essentially planar mol-ecules which make up the asymmetric unit have almost identical geometries and and are linked into dimeric aggregates via pairs of O-H⋯O hydrogen bonds. These aggregates have almost perfect inversion symmetry; however, quite unusually, the inversion center of the dimer does not coincide with the crystallographic inversion center.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
