Methyl Cyanodithioformate as a Reactive Dienophile in Diels–Alder Reactions

A Diels–Alder reaction between cyclopentadiene and methyl cyanodithioformate afforded a 60:40 mixture of the isomers 2a and b. The n.m.r. studies of these compounds and the products of LiAlH 4 reduction, 3a and b, established that the major isomer, 2a, was 3-exo-cyano-3-methylthio-2-thiabicyclo-[2.2... View More
