✦ Synopsis

Synthesis and Chemical Reactions of New Phosphono-Phosphino Substituted γ-Thiapyrones.

-The 1,3-dithietane-2,4-diylidenes (I) react with acylated acetonitriles to form γ-thiapyrones (III). Standard Boc-protection of (III) results in the reaction at the primary amino group and oxidative desulfurization leads to the γ-pyrones (VI). -(NEIDLEIN, R.;

The treatment of 4-chlorobutyronitrile, 3-chloropropyl phenyl sulfone, and other related compounds with a base afforded gamma-halocarbanions that undergo fast intramolecular substitution of the halogen to produce substituted cyclopropanes. We found that these short-lived carbanionic intermediates ca
