Stereodivergent Synthesis of Trisubstituted Enamides: Direct Access to Both Pure Geometrical Isomers

A stereodivergent strategy has been developed to access either (E)- or (Z)-isomers of trisubstituted enamides. Starting from an extensive range of ketones, it was possible to synthesize and isolate the desired pure isomer by switching the reaction conditions. Lewis acid activation enables the formation of the (E)-isomers in high stereoselectivity (>90:10) and good yields. On the other hand, the use of a Br¡ãnsted acid allows the preparation of the (Z)-isomers, again in high selectivity (up to 99:1), with moderate yields.

Interaction of substrate and catalyst during the formation of oxazolidinones from 2-aminoalcohols and diethyl carbonate using recyclable 1,3-dichlorodistannoxanes

An efficient synthesis of oxazolidinone (OXZ) using 2-aminoalcohols (2AAs) and diethyl carbonate (DEC) as reagents in the presence of recyclable catalyst 1,3-dichloro-1,1,3,3-tetraalkyldistannoxane, [(RR?SnCl)2O] 2 (1) is reported. 0.5 mol% (with respect to 2AA) of 1 provides OXZ quantitatively within 1 h at 80 C with turnover frequency (TOF) of 200 h-1. The observed TOF is much higher than the reported value (4 h-1) of the most convenient and commercially feasible K 2CO3 catalyst. Chiral 2AAs produce OXZs with 99% ee. Molar dependency of 1, DEC and 2AA is found to be 1:2:2. Molar conductivities (Omega-1 cm2 mol-1) in DMSO at 25 C are 6.41 for 1a (R = R? = Bu), 5.25 for 1b (R = Bu, R? = Ph), 2.87 for 1c (R = Ph, R? = Bu), and 2.21 for 1d (R = R? = Ph) which reveal the mobility of bridged Cl in 1 during reaction. The study of a broad range of substrates and reaction parameters supports a reaction pathway that begins with initial attack by -OH of the pre-formed 2-ethylcarbamato aminoalcohol (2ECA) of 2AA on Snb of 1 displacing the bridged Cl. Change in the reaction rates resulted due to various alkyl and aryl substituents on Sn provides better understanding of the distannoxane catalysis, which has not been attempted before for the said reaction.

Total synthesis of AI-77-B: Stereoselective hydroxylation of 4-alkenylazetidinones

A stereoselective synthesis of the anti-ulcer compound AI-77-B 1 is described. The 4-formylazetidinone 6 was converted into the 4-(Z)-alkene 23 using a phosphonate condensation, and dihydroxylation using osmium tetroxide and N-methylmorpholine W-oxide gave a mixture of the diols 24 and 25 in an 80:20, ratio. After protection of the diol 24 as its acetonide, hydrogenolysis gave the acid 27. The oxazoline 45 was deprotonated using butyllithium, and the lithiated oxazoline added to Cbz-protected leucinal 29, which had previously been deprotonated by tertbutylmagnesium chloride, to give the lactones 30 and 31, ratio 85:15, after treatment with silica in dichloromethane. Hydrogenolysis gave the aminolactone hydrochloride 52 which was condensed with the acid 27 to give the protected dipeptide 54. Deprotection under acidic conditions gave the dihydroxyazetidinone 55. Treatment with sodium hydroxide followed by acidification then gave the aminolactone hydrochloride 56 which on further treatment with sodium hydroxide followed by acid gave AI-77-B methyl ether 58. Demethylation of the phenolic methyl ether 30 followed by hydrogenolysis of the Cbz-protecting group gave the aminophenol 60 which was coupled with the acid 27 and the product taken through to AI-77-B 1 following the sequence used to prepare the methyl ether 58.

Two solvents of this reaction, sulfolane and trifluorotoluene, were compared at 210 C and the former consistently led to higher yields. In addition, these studies confirmed the importance of the steric bulk of the C5-position of the pyrimidinyl cycloaddition precursor.

Structure-activity relationship study to understand the estrogen receptor-dependent gene activation of aryl- and alkyl-substituted 1H-imidazoles

A series of C5-substituted 1,2,4-triaryl-1H-imidazoles was synthesized. Their gene-activating properties were determined on estrogen receptor alpha positive MCF-7 breast cancer cells, stably transfected with the plasmid ERE wtcluc (MCF-7-2a cells). The influence of 4-OH and 2-Cl substituents on the phenyl rings as well as the significance of a methyl, ethyl, or phenyl group at C5 on the estrogen receptor binding and the resulting gene activation in MCF-7-2a cells was studied. The alkyl and aryl groups at C5 of 1,2,4-tris(4-hydroxyphenyl)-1H-imidazole 1 increased the transactivation, while chlorine atoms on the phenyl rings diminished this effect. 5-Ethyl-1,2,4-tris(4- hydroxyphenyl)-1H-imidazole 9 was identified as the most active compound. Its excellent transcriptional activity did not only depend on the C5 ethyl group, but also on the three hydroxyl groups of the phenyl rings. Compounds (11-14) with a reduced number of hydroxyl groups displayed distinctly lower gene activation.

Gold-catalyzed nitrene transfer to activated alkynes: Formation of alpha,beta-unsaturated amidines

A gold-catalyzed intermolecular nitrene transfer to alkynes was developed for the first time, revealing a new mode of nitrene transfer and providing a novel access to versatile alpha-imino metal carbenes. Various mild nitrene-transfer reagents were examined, and iminopyridium ylides especially those based on 3,5-dichloropyridine proved be highly effective. With activated alkynes such as N-alkynyloxazolidinones as substrates, alpha,beta- unsaturated amidines were formed in mostly good yields.
