    日期:2008.2.1
    A novel synthesis of highly substituted acryl imide derivatives by the three-component reaction of allenoates, isocyanides, and carboxylic acids was reported, and the intramolecular cyclization reaction of allenoic acids with isocyanides was also described.

    boxylic acids and their esters) undergo partial hydrodebromination at the treatment with isopropyl magnesium bromide (3–6 mol-equiv) in THF and then in methanol at −60°C affording the corresponding monobromides in 64–95% yields. The addition of nonsolvated magnesium bromide to the reaction mixture results in the considerable reduction of the amount of the Grignard reagent (from 6 to 3 mol-equiv). This

    3-Methyl-1-phenylthio-1-trimethylsilylbuta-1,2-diene (3) reacts with different alkyl-lithium reagents by C–Si or C–S bond cleavage, rather than by Michael addition or metallation; one product, the α-silyl-α-lithioallene (6), is alkylated mainly γ with carbonyl compounds, but is silylated α with Et3SiCl to from the 1,1-bis-silylallene Me2CCC(SiEt3)SiMe3.

    Triple‐decker sandwich: A sandwich‐type triple cyclization of two molecules of 2,3‐allenoic acid and one molecule of 1,5‐bisallene in the presence of a palladium catalyst with excellent stereoselectivity has been developed. The diallyl‐substituted cis products may easily be transformed to fused tetracyclic compounds with a 12‐membered ring (see scheme). Based on the result of optically active 2,3‐allenoic
