Abstract
2-Alkyl- or phenyl-substituted 4-methoxy-4-(1-methylethenyl)-2-cyclobutenon es react with 2-lithiopropene or alpha-lithiostyrene to produce 4-methoxy-2 ,4-cyclooctadienones in moderate yield, accompanied by varying amounts of 4 -methoxy-4-(1-methylethenyl)-2-cyclohexenones. The reaction is general for 2-alkyl substituted 4-methoxy-4-(1-methylethenyl)-2-cyclobutenones. (C) 200 0 Elsevier Science Ltd. All rights reserved.
