Methylenecyclopropane Ring-Expansion with SO2: Synthesis and Applications of Novel γ-Sultines
Balticum Organicum Syntheticum 2024: Abstract Book 2024
Emanuels Šūpulnieks, Māris Turks

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
