A one-pot synthesis of polysubstituted benzene derivatives was achieved via a platinum(IV)-catalyzed intramolecular cycloaromatization reaction. The reaction proceeds via a tandem skeletal rearrangment, dehydration and double bond isomerization, which proved to be very useful for the syntheses of a range of interesting polyalkyl-substituted benzenes.

Page/Page column 2, (2010/05/13)
The invention relates to the use of 5,5-dimethyl-3-ethyl-3,4-dihydrofuran-2-one (A), named “Noxolide” by the applicant, as an olfactory agent in perfumery, and also as a food flavouring. The invention also relates to a novel process for the preparation of 5,5-dimethyl-3-ethyl-3,4-dihydrofuran-2-one.

(Chemical Equation Presented) Intramolecular additions of hydroxyl or carboxyl groups to inert olefins catalyzed by simple silver(I) triflate are described. Good to excellent yields can be obtained for a range of substrates under relatively mild conditions. This reaction represents one of the simplest methods to construct cyclic ethers or lactones.
Bis(aminophosphine)-nickel complexes as efficient catalysts for alkylation of allylic acetates with stabilized nucleophiles
Bricout, Herve,Carpentier, Jean-Francois,Mortreux, Andre
, p. 6105 - 6108 (2007/10/03)
The alkylation of a variety of allylic acetates with dimethyl malonate catalysed by nickel-diphosphine complexes is reported. It is shown that in most cases bis(aminophosphine) type ligands lead to much more efficient catalysts than dppb and other usual d
