A simple and efficient protocol has been developed for the synthesis of 3-aroylimidazopyridines via copper(II) acetate-catalyzed aerobic oxidative amination. A library of 3-aroylimidazopyridines was synthesized from readily accessible chalcones and 2-aminopyridines with high yields and regioselectivity. The reaction proceeds through a tandem Michael addition followed by an intramolecular oxidative amination. The successful application of this methodology for a gram-scale reaction indicates its potential for bulk synthesis.

Each of the chiral 1,2- and 1,3-diols examined was derivatized exclusively to a single diastereomeric acetal by the use of a new axially chiral reagent, 2?-methoxy-1,1?-binaphthalene-8-carbaldehyde (MBC). The absolute configuration of the original 1,2- and 1,3-diols was determined by the NOE correlation between the proton signals of the reagent moiety and those of the diol moiety in the acetals.

We have developed a new sulfenylation reagent, 3-phenylsulfenyl-2-(N- cyanoimino)thiazolidine 3, that is readily available and stable upon storage. Compound 3 easily reacts with amines or thiols to give the corresponding sulfenamides or asymmetrical disulfides in excellent yields. It was also found that the alpha-sulfenylation reaction of carbonyl compounds with 3 proceeds smoothly. Furthermore, optically active 4-diphenylmethyl derivative 4 was synthesized as an asymmetric sulfenylation reagent, which realized 96% e.e. upon alpha-sulfenylation of a cyclic beta-keto ester.

Eleven new chiral macrocycles (1-11, see Figure 1) of the pyridino-18-crown-6 type have been prepared.Nine diazapyridino-crown ligands contain two amide (1, R = benzyl; 4, R = phenyl), two N-methylamide (7, R = phenyl), two thionoamide (2, R = benzyl; 5, R = phenyl), two N-methylthionoamide (8, R = phenyl), two amine (3, R = benzyl; 6, R = phenyl), or two N-methylamine (9, R = phenyl) groups incorporated into the macroring.The appropriate chiral diamine was treated with dimethyl 2,6-pyridinedicarboxylate (or 2,6-pyridinedicarboxyl dichloride),O,O’-dimethyl 2,6-pyridinedicarbothioate, or 2,6-pyridinedimethyl ditosylate to prepare these materials.The macrocyclic diamides were also converted to the macrocyclic dithionoamides using Lawesson’s reagent and the latter macrocycles were reduced to the diamines.A new symmetrically substituted dimethylazapyridino-18-crown-6 ligand (10) and its N-acetyl derivative 11 were also prepared.The interactions of some of the new chiral ligands with (R)- and (S)-ammonium perchlorate were studied by 1H NMR spectral techniques.The degree of enantiomeric recognition was determined by the difference of the free energy of activation values (DeltaDeltaGexcit.) and the difference in log K values for these interactions.The X-ray analyses of the dithionoamido ligands (2, 5, and 8) showed severe deviations of the S and N atoms from the plane of the pyridine ring, especially in the case of 8.The optical rotations of 8 changed with time due to conformational changes.The relevant conformations of 8 are discussed in light of the X-ray crystallography, molecular mechanics, and 1H NMR spectra.

The enantiomers of proxyphylline have been separated via their corresponding camphanates. Synthesis of (+)-proxyphylline from theophylline and (S)-propylene oxide derived from (S)-lactic acid established the absolute configuration of the (+) and (-) isomer as S and R, respectively. The activity of the enantiomers as cyclic nucleotide phosphodiesterase inhibitors was tested in human lung tissue homogenate. No differences were found either between the two enantiomers or between the enantiomers and racemic proxyphylline.
