supporting information; experimental part, p. 828 - 831 (2012/03/07)
In the presence of a Cu(I) catalyst and a pyridine oxide, alkynyl oxiranes and oxetanes can be converted into functionalized five- or six-membered α,β-unsaturated lactones or dihydrofuranaldehydes. This new oxidative cyclization is proposed to proceed via an unusual allenyloxypyridinium intermediate.

-
, (2008/06/13)
Process for preparing 5-fluoro-2-methyl-1-(p-methylsulfinylbenzylidene)-indene-3-acetic acid by reacting fluorobenzene with an acid halide, to form an indanone, reaction of the indanone with a methylthio (or methylsulfinyl)benzyl compound to form 5-fluoro-2-methyl-1-(p-methylthiobenzyl) or (p-methylsulfinylbenzyl)-indene and reacting said indene with a glyoxylic acid. The invention also relates to intermediates thereof and processes for said intermediates.
