Synthesis of Functional Dihydro-1,4-benzoxaselenins from Allyl Ether of Carvacrol and Selenium Dihalides
Selective one-pot methods for the synthesis of functional 2,3-dihydro-1,4-benzoxaselenins in 90-98% yields have been developed based on the reactions of annelation-selenofunctionalization of the allyl ether of carvacrol with selenium dihalides. The first example of annulation-acetoxyselenation reaction was shown.
