Conrads, Martin published the artcileCycloadditions. 32. Convenient methods for the preparation of sulfur substituted allenecarboxylates, COA of Formula: C10H16O2, the publication is Synthesis (1991), 11-14, database is CAplus.
2-Sulfinyl- and 2-sulfonylallenecarboxylates, as new 1,1-diacceptor substituted allenes, were prepared starting from Me 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.
