Kohl-Mines, Elisabeth,Hansen, Hans-Juergen
, p. 2244 - 2248 (1985)
It is shown that carboxylic acids, in the presence of Bu3N and 2-chloro-1-methylpyridinium iodide in toluene or CH2Cl2, react with phosphoranes to yield the corresponding esters of allene carboxylic acids (cf.Scheme

Rhodium(III)-catalyzed annulative coupling of sulfoxonium ylides with allenoates was achieved, forming highly functionalized cyclopropanes with a quaternary carbon center by means of the sulfoxonium ylide functionality as a traceless bifunctional directin

In this paper, a phosphine-catalyzed [8 + 2]-annulation of heptafulvene with allenoates has been achieved under mild conditions, giving functionalized bicyclo[5.3.0]decane derivatives in moderate to excellent yields. Using chiral phosphine as the catalyst, optically active products were obtained in moderate to high yields with excellent enantioselectivities.
