Abstract
An easy, two-step approach to various 5-carboxymethyl-2(5H)-furanones is described. A detailed study of the reaction of β-carboxymethyl enamino esters with N-bromosuccinimide is presented.
Key words
tetronamides - 4-amino-2(5H)-furanones - bromocyclization - alkylation - decarborxylation

structure leads to a geometry that was first improved using molecular
mechanics techniques (MM2) implemented in Chem3D 5.0, and the resulting
structure was optimized by the semiempirical Hamiltonian AM1 then
at the ab initio STO3G level in the GAMESS
suite of programs.
