    摘要:
    Methoxymethylene Meldrum's acid 2 in acetonitrile solution acts as a useful C-electrophile for active substrates such as pyrrole, indole or tertiary enaminones to give substitution products (e.g. 5, 6 or 12, respectively). Primary enaminones react exclusively at the nitrogen atom under these conditions. The effect of ring substituents on the regiochemistry of electrophilic substitution of 3-hydroxypyrroles and 3-methoxypyrroles was studied using methoxymethylene Meldrum's acid as the electrophile. Flash vacuum pyrolysis of the Meldrum's acid derivatives obtained in many of these reactions gave access to a range of heterocyclic systems, including the pyridone 48, quinolinedione 43, benzazepinedione 41 and fused pyrones 50, 52 and 54.

    Alkylation of 1 -substituted 1 H-pyrrol-3(2H)-ones 1 in the presence of base generally gives a mixture of O-alkylated 3, C, O-dialkylated 4 and C, C-dialkylated 5 products. The proportion of C-alkylation is increased by the use of a soft alkylating agent (e.g. iodomethane) and a solvent of low polarity (e.g. THF), whereas O-alkylation is favoured by hard alkylating agents (e.g. methyl toluene-psulphonate)
