✦ Synopsis

When 1,2,3-selenadiazoles were treated with an excess amount of olefins in the presence of a catalytic amount of Bu3SnH and AIBN, the addition of a vinyl radical, which was generated in situ by the denitrogenation of 1,2,3-selenadiazoles, to the carbon-carbon double bond followed by intramolecular cyelization proceeded efficiently to afford the corresponding dihydroselenophenes in moderate to good yields.

An interesting 2,4-syn dialkyl diastereoselection has been observed in the radical debromination of a-bromo-a-methyld-valerolactones. The reaction of 4-alkyl-2-bromo-3-hydroxy-2-methyl-5-pentanolides with Bu 3 SnH and a catalytic amount of Et 3 B gave, essentially, a single diastereomer with a 2,4-s
