The pyrolysis of 3-methyl-3-acetyl-Δ1-pyrazoline (IV) and cis- and trans-3,5-dimethyl-3-acetyl-Δ1-pyrazoline (V and VI) has been studied. Pyrolysis of IV gave 2,3-dimethyl-4,5-dihydrofuran (XI) as a minor product, indicating some ring closure to oxygen in these reactions. Pyrolysis of V gave 2,3,5-trimethyl-4,5-dihydrofuran (XVII) as 23% of the product, whereas VI yielded only a trace of XVII. This fact and other differences in the product analysis from isomers V and VI are discussed in terms of the possible mechanism for the pyrolysis reaction.
