The effect of cyclohexene ring conformation on the diastereoselectivity observed for Simmons-Smith cyclopropanation of 2-cyclohexen-1-one ethylene ketals was examined by using (5S)-5-tert-butyl-2-cyclohexen-1-one 1,2-ethanediol, (2R,3R)-2,3-butanediol, and (2S,3S)-2,3-butanediol ketals.Reagent chelation by the pseudoequatorial dioxolane oxygen atom was shown to result in more effective methylene transfer.This regiochemical preference can either antagonize or reinforce diastereoselectivity due to steric hindrance of the dioxolane oxygen atoms from dissymmetric placement of methyl appendages on the dioxolane ring.

A general and reliable method for the resolution of racemic 1,3-alkanediols, which involves their conversion into diastereomeric spiroacetals derived from l-menthone, is described.Thus, the reaction of the bis-O-trimethylsilyl derivatives of racemic 1,3-alkanediols with l-menthone in the presence of a catalytic amount of trimethylsilyl trifluoromethanesulfonate affords the diastereomeric spiroacetals 3 and 4.The two can be readily separated by silica gel column chromatography.Hydrolysis of each diastereomer under acidic conditions liberates the corresponding enantiomerically pure diol.An empirically derived correlation of configuration and 1H NMR chemical shifts for spiroacetals 3 and 4 has been developed which is rationalized based on long-range effects due to the magnetic anisotropy inherent to the menthane ring in a rigid spiroacetal conformation.The method described here should be widely applicable to the determination of the absolute configuration of various 1,3-alkanediols.

(Chemical Equation Presented) Di(1-naphthy)ketals of 1,n-diols show couplet effects allied to the 1B naphthalene transition in their CD spectra. This means that they assume a conformation with a prevailing sense of twist of the naphthalene rings, imposed by the absolute configuration (AC) of the starting diols and by the nature of the R1 groups. A positive couplet for aliphatic diols is a probe of (R,R), AC while the opposite sign is found for (R,R) aromatic diols.

Optically active poly(y-ketosulfide)s can be obtained by polyaddition of 1,3-dimercaptobenzene to prochiral di-unsaturated ketones in the presence of (-)-cinchonidine as promoter of asymmetric induction. As proved with low molecular-weight model compounds, the enantiomeric excess found in the addition product is related to steric hindrance and conformational rigidity of the ketonic reagent as well as to reaction temperature, in accordance with the high sensitivity of this type of homogeneous catalysis to substrate structure and experimental conditions.

New chiral mexiletine analogs were synthesized in their optically active forms and evaluated in vitro as use-dependent blockers of skeletal muscle sodium channels. Tests carried out on sodium currents of single muscle fibers of Rana esculenta demonstrated that all of them exerted a higher use-dependent block than mexiletine. The most potent analog, (S)-3-(2,6-dimethylphenoxy)-1- phenylpropan-1-amine (S)-(5), was six-fold more potent than (R)-Mex in producing a tonic block. As observed with mexiletine, the newly synthesized compounds exhibit modest enantioselective behavior, that is more evident in 3-(2,6-dimethylphenoxy)butan-1-amine (3).
