EFFECT OF ANNELATION ISOMERISM ON OPTICAL PROPERTIES OF SOME THIONAPHTHENE DERIVATIVES. PART V. 2-NAPHTHO--THIENYLSULFINYLACETIC ACIDS AND SOME OF THEIR DERIVATIVES

The synthesis and principal properties of 2-naphtho--thienyl-sulfinyl>- and sulfonylacetic acids as well as of some of their derivatives have been described.The racemic acid has been resolved by crystallization of its diastereomeric salts with optically active bases.The absolute configurations of the enantiomers have been elucidated.Optical rotatory dispersion of the laevorotatory enantiomer and its methyl ester and N-methylamide in the region of 360 under λ under 623.4 nm have been determined.Seven-term equations describing optical rotation of the dextrorotatory enantiomer in the studied spectral region have been derived.Racemization constants (K) and activation parameters (Ea, ΔS(excit.), ΔH(excit.)) of racemization of the laevorotatory 2-naphtho--thienylsulfinylacetic acid have been determined by classical kinetic methods.
