Abstract
Cu(I)Cl decomposition of the phenyliodonium ylides derived from o-, m- and p-methoxyphenyl-3-ketopentanoic acid methyl esters affords the co rresponding 5-, 6- and 7-methoxy-1-carbomethoxy-2-tetralones in prepar ative yields. The lower homologous phenyliodonium ylides derived from o-, m- and p-methoxyphenyl-3-ketobutyric acid methyl esters yield the analogous 1-carbomethoxy-2-indanone only in the meta-methoxyphenyl cas e, and the ortho- and para-methoxyphenyl substituted iodonium ylides y ield dimeric products.
