Webethyl 4-chloroacetoacetate promoted by Ti(OiPr) 3Cl at 95 °C (Scheme 5). This reaction has been successfully applied to the synthesis of julolidine-fused analogues.31–33 Unfortunately, this route was unsuccessful because at these high temperatures even the chloride ion, a poor nucleophile, attacked the azetidine WebEthyl acetoacetate is subject to keto-enol tautomerism. In the neat liquid at 33 °C, the enol consists of 15% of the total. Multicarbon building block. Ethyl acetoacetic acid is a building block in organic synthesis since the protons alpha to carbonyl groups are acidic, and the resulting carbanion undergoes nucleophilic substitution.
