Page/Page column 24, (2016/06/01)
The present invention relates to core-shell microcapsules comprising photolabile 2-oxoacetate pro-fragrance molecules capable of liberating an active molecule such as, for example, an aldehyde or ketone upon exposure to light. The present invention concerns also the use of said microcapsules in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's microcapsules to provide a prolonged release of fragrant aldehydes and/or ketones.
Photolabile latex for the release of perfumes

Page/Page column 21, (2016/05/19)
The present invention relates to the field of perfumery. More particularly, it concerns co-polymeric latex particles derived from 2-oxo-2-(3- or 4-vinylphenyl)acetates capable of liberating an active molecule such as, for example, an aldehyde or ketone up
Phase-vanishing reactions with ptfe (teflon) as a phase screen

Phase-vanishing reactions are triphasic reactions, which involve a reagent, a liquid perfluoroalkane, and a substrate. In a phase-vanishing reaction with PTFE tape as the phase screen instead of a liquid perfluoroalkane, there is no limitation related to the density of a phase and the denser phase can be in the top layer. The reactions were faster compared to traditional PV reactions, and it was possible to carry out sequential and tandem reactions and reactions under a reflux.
Asymmetric synthesis of chiral α-keto esters via Grignard addition to oxalates

While enroute to an asymmetric synthesis of the chlorine containing metabolite (-)-cryptosporiopsin an efficient and reliable asymmetric synthesis of chiral α-keto esters was required. These compounds can be conveniently generated in 51-84% yields via Gri
Alkylation of Aromatic Heterocycles with Oxalic Acid Monoalkyl Esters in the Presence of Trivalent Iodine Compounds
Togo, Hideo,Aoki, Masahiko,Yokoyama, Masataka
, p. 1691 - 1694 (2007/10/02)
Aromatic heterocycles containing nitrogen atoms were easily alkylated with the half esters of oxalic acid, which were prepared from alcohols, in the presence of benzene via radical decarboxylative pathways.This is the first method for the alkylation of aromatic heterocycles with alcohols via the formation of half esters of oxalic acid.
