Perillene is an essential ingredient in a Chinese patent drug and features some fascinating biological activities. We present herein an efficient pathway to perillene that hangs on the cross-coupling reaction of allylic carbonates with furfuryl Grignard r

(matrix presented) Trisulfide 2-oxide 11 has been prepared from disulfide 9 via reduction to the corresponding dithiol and subsequent trapping with thionyl chloride. Heating trisulfide oxide 11 in the presence of dienes results in transfer of sulfur monoxide to form cyclic unsaturated sulfoxides 13 in good to excellent yields, along with recovery of disulfide 9. A Pummerer reaction can be used to convert the cyclic sulfoxides into thiophenes.
Selective Alkylation and Allylation of Allylic Halides by Tetraorganoidates: Regio- and Stereo-selective Synthesis of Rosefuran and Sesquirosefuran

Tetraalkylindanes regioselectively alkylate allylic bromides at the α-carbon.In this way, 1,5-dienes have been regio- and stereo-selectively synthesized by the allyl-allyl coupling of allylic bromides and allylic indates, including rosefuran 1 and sequirosefuran 3.
