β-Phenylsulphinyl-nitro-alkenes (7) are readily prepared from acyl imidazoles and react as nitroacetyleneequivalents in Diels–Alder reactions to give good yields of cycloadducts and their further products.
A simple approach to alkylated nitroaromatics from substituted nitroaryl malonic esters by double decarboxylation is detailed.

The present invention discloses novel and improved nucleosidic and nucleotidic compounds that are useful in the light-directed synthesis of oligonucleotides, as well as, methods and reagents for their preparation. These compounds are characterized by novel photolabile protective groups that are attached to either the 5′- or the 3′-hydroxyl group of a nucleoside moiety. The photolabile protective group is comprised of a 2-(2-nitrophenyl)-ethyoxycarbonyl skeleton with at least one substituent on the aromatic ring that is either an aryl, an aroyl, a heteroaryl or an alkoxycarbonyl group. The present invention includes the use of the aforementioned compounds in light-directed oligonucleotide synthesis, the respective assembly of nucleic acid microarrays and their application.
