Preparation of 3-Alkoxy-4-alkyl-3-cyclobutene-1,2-diones

Several squaric acid esters (2a-g) are prepared.They react with Grignard compounds to give the title compounds (11a-n). 1,2- vs. 1,4-Grignard addition and the benzyl-tolyl rearrangement coincidental with the Grignard reaction are discussed.Hydrolysis of compounds 11 leads to 4-alkyl-3-hydroxy-3-cyclobutene-1,2-diones (12).
