Abstract
The synthesis and resolution of rac-6-hydroxy-3-methoxycyclohex-2-enone, by fractional crystallization of diastereomeric esters of N-protected (S)-proline was shown to be an effective method for preparation of both pure diastereomers (>95% d.e., according to (1)H NMR data). The absolute configuration of the asymmetric center in cyclohexene ring was determined based on the inversed octant rule for the sign of circular dichroism for these cyclohexenones (n-pi*-transition band at approximately 300 nm) and further substantiated by chemical conversion of the (-)-(6R,2'S)-diastereomer into the known (+)-(R)-4-hydroxycyclohex-2-enone.

Abstract
Deoxycorticosterone (DOC) derivative compounds (DOC, DOC 21-acetate, and 7-mercaptopropionic DOC) have been prepared and purified by high pressure liquid chromatography. Synthesis products have been identified, and three chromophores have been displayed by their n----II and II----II dichroic transitions. A normal half-chair conformation is favored in ring A.

Abstract
The absolute configurations of the enantiomers of N,N,1-trimethyl-cis- and trans-1-phenyl-1,2,3,4-tetrahydro-3-naphthylamines (Ia and Ib) were assigned tentatively from the circular dichroism spectrum of a bridged ketone derived by cyclization of optically active 1-methyl-cis-1-phenyl-1,2,3,4-tetrahydro-3-naphthoic acid (IIa). Thus, (--)-IIa and the corresponding amine, (--)-Ia, were assigned the (2S, 4R)-configuration. Epimerization of (--)-IIa through its methyl ester yielded the trans-acid, (--)-IIb, which established the absolute configuration of (--)-IIb and the corresponding amine, (--)-Ib, as (2R, 4R).
