An unexpected acid-mediated cascade reaction induced by conjugate addition of sulfinamides to dienediones has been developed. This highly efficient Rauhut-Currier reaction enables the rapid, high-yielding construction of sulfonated cyclopentanes with three contiguous stereogenic centers in a single operation starting from simple sulfinamides. This process constitutes the first example of sulfinamide-promoted cycloisomerization.
