One-Pot Syntheses of Functionalized Dihydrobenzoselenophenes and Selenochromans from Acetyl Eugenol and Selenium Dibromide. Rearrangement of 2-(Bromomethyl)-2,3-dihydro-1-benzoselenophene to Selenochromans
Efficient methods for the synthesis of new fused heterocyclic compounds have been developed on the basis of annulation–functionalization of acetyl eugenol with selenium dibromide. The proposed procedures make ...

Synthesis of Functional Dihydro-1,4-benzoxaselenines from Carvacrol Allyl Ether and Selenium Dihalides
One-step procedures have been developed for the selective synthesis of functionalized 2,3-dihydro-1,4-benzoxaselenines in 90–98% yields by cyclization of carvacrol allyl ether with selenium dihalides. Annulati...

Immunotropic Properties of an Experimental Synthetic Selenium-Organic Compound
We studied immunotropic properties of synthetic selenium-organic preparation 2,6-dipyridinium-9-selenabicyclo[3.3.1]nonyl dibromide (974zh). The experimental preparation reduced the cAMP/cGMP ratio, which indi...

Regio- and Stereoselective Addition of Selenium Dichloride to Alkyl Propiolates
The reaction of selenium dichloride with methyl and ethyl propiolates leads to formation of anti-Markovnikov adducts. The regio- and stereoselective synthesis of hitherto unknown bis[(E)-2-chloro-1-(alkoxycarbony...

Synthesis of Functionalized Diorganyl Selenides from Selenium Dihalides and Allylic Aromatic Compounds
Hitherto unknown addition and methoxyselenation reactions of selenium dihalides with methyl eugenol and allyl naphth-1-yl ether were studied. The addition and methoxyselenation reactions of selenium dihalides ...
