Trimethyl Phosphite Mediated Simple Synthesis of Coumarins and Azacoumarins Through the Reaction of Phenols or Hydroxypyridines and Dimethyl Acetylenedicarboxylate (DMAD) or Diethyl Acetylenedicarboxylate (DEAD)
Protonation of the reactive intermediate produced in the reaction between trimethyl phosphite and dimethyl acetylenedicarboxylate or diethyl acetylenedicarboxylate by resorcinol, 5-methylresorcinol, 2,5-dihydroxyacetophenone, 4-chloro-2-methylphenol, 4-chloro-3,5-dimethy-lphenol, 4-hydroxypyridine, 2-hydroxypyridine, 3-hydroxypyridine, or 8-hydroxyquinoline leads to vinylphosphonium salts,...
متن کاملCrystal structure of diethyl 2-acet-oxy-2-[3-(4-nitro-phen-yl)-3-oxo-1-phenyl-prop-yl]malonate.
In the racemic title compound, C24H25NO9, the dihedral angle between the planes of the two benzene-ring systems is 80.16 (6)°, while the side-chain conformation is stabilized by a methyl-ene-carboxyl C-H⋯O hydrogen bond. Weak inter-molecular C-H⋯O hydrogen bonds form inversion dimers [graph set R 2 (2)(16)] which are linked into chains extending along a. Further C-H⋯O hydrogen bonding extends t...
متن کامل(E)-1-Nitro-4-(2-nitroethenyl)benzene
The asymmetric unit of the title compound, C(8)H(6)N(2)O(4), consists of two independent mol-ecules with similar geometries, each adopting a trans configuration about the olefinic double bond. The two mol-ecules are both almost planar (r.m.s. deviations = 0.034 and 0.035 Å) and form a dihedral angle of 83.62 (2)°. Short N⋯O contacts [2.834 (3)-2.861 (3) Å] are observed between the nitro groups ...
