Article abstract of DOI:10.1246/bcsj.55.333

The cycloaddition reaction of 2-benzylidenetetralin-1-thione S-oxide with acrylonitrile (or styrene) gave a mixture of 2- and 3-cyano(or phenyl)-4-phenyl-3,4,5,6-tetrahydro-2H-naphtho<1,2-b>thiopyran S-oxide.Pummerer reaction of these S-oxides resulted to afford the corresponding acetates
