Aza-Diels-Alder reactions of 2-(phenylthio)-1,3-butadiene with simple iminium salts
Chou,Hung
, p. 1097 - 1104 (2001)
The titled compound 2 was readily prepared by thermal desulfonylation of 3-(phenylthio)-3-sulfolene (1). The aza-Diels-Alder reactions of 2 with some simple iminium salts gave the cyclized products 3-7 in good yield with complete control of regiochemistry
THE EFFECT OF SULFUR AND SELENIUM SUBSTITUTENTS ON THE REGIOCHEMISTRY OF DIELS-ALDER REACTIONS
Liotta, Charles L.,Verbicky, John W.
, p. 1395 - 1398 (2007/10/02)
2-Phenylthio-1,3-butadiene (1) and 2-phenylseleno-1,3-butadiene (2) have been generated in situ from their SO2 adducts and reacted with a series of unsymmetrical dienophiles.The regiochemical results have been analyzed in terms of qualitative perturbation
