The reaction of 2,6-dimethyl-3,5-diphenyl-4H-pyran-4-thione with dimethyloxosulfonium methylide occurred facilely to give two kinds of 2-thienylacetones, accompanied by a five-membered α,β-unsaturated thione, a naphtho-[2,1-b]thiophene derivative, and a hemithioacetal.
2,6-二甲基-3,5-二苯基-4H-吡喃-4-硫酮与二甲基氧锍甲基化物的反应很容易得到两种2-噻吩基丙酮,并伴随有一种五元α,β-不饱和硫酮,一种萘并[2,1-b]噻吩衍生物和半硫缩醛。
