    Nonionic Superbase-Promoted Synthesis of Oxazoles and Pyrroles: Facile Synthesis of Porphyrins and .alpha.-C-Acyl Amino Acid Esters
    摘要:
    The reaction of acyl chlorides or acid anhydrides with isocyanoacetates in the presence of the superior strong nonionic base P(MeNCH(2)CH(2))(3)N (1) gave oxazoles in 98-99% yield. Treatment of the oxazoles with HCl-MeOH gave alpha-C-acyl amino acid esters in 81-82% yield. The reaction of beta-acetoxy-alpha-nitroalkanes or nitroalkenes with isocyanoacetates in the presence of 1 gave pyrroles in 100% yield. The conjugate acid of 1 can be treated with KO-t-Bu to regenerate 1. Treatment of the pyrroles with LiAlH4, followed by PTSA-CH2(OMe)(2) and oxidation gave porphyrins in 65-69% yield. LiCl, which functions both as a strong nucleophile in the S(N)2 demethylation of the 5,5'-bis(methoxycarbonyl)-3,3',4,4'-tetramethyldipyrromethane 22a and as a Lewis acid in the electrophilic substitution cyclization of paraformaldehyde at dipyrromethane, facilitates the combination of four reactions into a one-pot synthesis of octaethylporphyrin in 67% yield from 22a.

    The present invention provides certain non-symmetric tripyrranes; that is, tripyrranes that do not contain a mirror plane of symmetry perpendicular to the plane containing the tripyrrane. Further, the invention includes texaphyrin compounds and sapphyrin compounds, as well as other polypyrrolic macrocycles, prepared using tripyrranes of Formula I as a precursor. These macrocycles are characterized by a tripyrrolic portion of the macrocyclic ring having substituents that cause the heterocycle to lack a plane of symmetry perpendicular to the plane of the macrocycle.
