2-Sulfinyl- and 2-sulfonylallenecarboxylates, as new 1,1-diacceptor substituted allenes, were prepared starting from methyl 4-hydroxy-4-methyl-2-pentynoate by a [2,3]-sigmatropic rearrangement. The sulfoxides could be reduced to the corresponding allenyl sulfides. A 2(5H)-furanone derivative was prepared by a side-reaction.
2-亚硫酰和2-磺酰丙烯酸酯,作为新的1,1-二受体取代的丙烯,是通过[2,3]信号转变重排从甲基4-羟基-4-甲基-2-戊炔酸酯合成的。该亚砜可被还原为相应的丙烯硫化物。通过副反应制备了一种2(5H)-呋喃酮衍生物。
