a-Allenylcyclopropanedicarboxylates, for which a novel synthetic method has been devised by conjugate addition of a copper hydride (Stryker) reagent to a-cyclopropylpropargylic esters, have been newly found to be smoothly converted to methylenecyclopentene derivatives under mild reaction conditions

Addition of sulfur dioxide to conjugated dienes has been known for many years. I,2 Usually 2,5-dihydrothiophene-1,1-dioxides (sulfones) are formed. Recently334 however, two highly reactive 1,3-dienes have been reported to yield 3,6-dihydro-1,2-oxathiin-2-oxides (sultines).
