A survey of mono- or bis-decarboxylation of β-methyl polyethylenic-malonic acids
摘要:
Diverse experimental conditions, leading to mono- or bis-decarboxylation of beta-methyl polyethylenic-malonic acids, were examined. A clean and easy bis-decarboxylation was reported. (C) 2003 Elsevier Science Ltd. All rights reserved.

SYNTHESIS OF NEW γ- AND δ-LACTONES BY ACID CYCLIZATION OF 2,4-DIETHYLENIC-DIACIDS
We have developed an easy synthesis for newγ- and δ-lactones. Acid-catalyzed cyclization of 2,4-diethylenic-diacids yields new γ or δ-lactones, depending on the substitution pattern of the unsaturated side chain.
