Sultines, cyclic esters of sulfinic acid, are employed in fragrance industry,1
are known
lactone bioisosters2
and are versatile sulfur-containing intermediates for synthesis of
various biologically active substances.3 Herein we describe novel γ-sultine 2a,b synthesis
method through palladium-catalysed methylenecyclopropane 1 ring expansion with sulfur
dioxide. Obtained γ-sultines can be derivatized to sulfoxides 3 and they undergo novel
reactions yielding indenes 4, allylamines 5 and allylacetates 6
