Syntheses and CD Studies of 5α-Cholesteno-, -- and -pyrimidines

Syntheses of 5α-cholesteno- (5a), - (12a), and pyrimidines (15a) have been achieved by using hydroxymethylene derivatives of relevant cholestanones prepared from cholesterol (1).Their CD spectra exhibit at least three Cotton effects between 300 to 200 nm, a first CD band around 290, a second one around 260 and a third one around 220 nm.A quadrant rule is developed and applied to the determination of the first CD band, while a helicity rule is applicable to the third CD band.The first band is positive in the series, whereas it is negative in the and the series.The third band is negative in all three series. - Key Words: Cholestenopyrimidines / Circular dichroism / Quadrant rule of cholestenopyrimidines

Anoid Acetamidosulphenylation and Trifluoroacetoxysulphenylation of Steroidal Alkenes

Electrochemical acetamidosulphenylation of a number of steroidal alkenes is described via oxidation of diphenyl, di-p-tolyl, dibenzyl and dipropyl disulphide in acetonitrile.The regiochemistry and stereochemistry of addition are established by analysis of

The Octant Rule VIII. Variable Temperature Circular Dichroism Spectra of α-Methyl- and Methoxyl-Substituted 5α-Cholestan-2- and -3-ones.

2α- and 2β-methyl- and methoxy-5α-cholestan-3-ones and 3α- and 3β-methyl- and methoxy-5α-cholestan-2-ones have been synthesized and their variable temperature circular dichroism spectra obtained and analyzed.Rotatory strength (R) values for α-axial and equatorial CH3 and OCH3 groups are determined by difference measurements with the parent ketone.The (small) equatorial CH3 R-values do not consistently follow the Octant Rule.Axial OCH3 groups do not obey the Octant Rule ("anti-octant" behavior) and impose a bathochromic shift on the C=O n-?* transition.Equatorial OCH3 groups do not consistently follow octant or "anti-octant" behavior.
