  N-Phenylselenosaccharin (NPSSac): a new electrophilic selenium-containing reagent

  摘要：

  A new reagent N-phenylselenosaccharin (NPSSac) was simply prepared and used as a source of the electrophilic phenylselenyl group. This relatively stable new compound was able to react with a series of electron rich organic molecules like alkenes in the presence of external or internal nucleophiles, activated aromatic substrates, or enolizable carbonyl derivatives, under very mild experimental conditions.

  日期：2020.6

  Integrated electrochemical reactors in automated flow systems were utilised for selenenylation reactions. The automation allowed multiple electrochemical reactions of a programmed sequence to be performed in a fully autonomous way. Many functionalised selenenylated­ products were synthesised in short reaction times in good to high yields.

  日期：2010.11

  Studies on the phenylselenoetherification of some Δ4‐alkenols in the presence of pyridine and some Lewis acids are described. All alkenols underwent intramolecular cyclization yielding corresponding tetrahydrofuran or tetrahydropyran derivatives. Yield and diastereomeric ratio of the cyclic products depend on counterion of selenylating reagent used. We found that external additives, such as pyridine

• Organoselenium-induced cyclizations in organic synthesis
  作者：K.C. Nicolaou

  DOI：10.1016/s0040-4020(01)93285-5

  日期：——

  A number of organoselenium reagents are introduced as efficient initiators of ring closures leading from unsaturated substrates to lactones, cyclic ethers, cyclic thioethers, N-heterocycles and carbocycles. These cyclizations often proceed with high ring selectivity and stereoselectivity and are accompanied by the incorporation of the phenylseleno group (PhSe) into the final product. Methods are described
