PREPARATION, ISOLATION AND CHARACTERIZATION OF POSITIONAL ISOMERS OF TRIGLUCOPYRANOSYLCYCLOMALTOHEPTAOSE

The positional isomers of triglucopyranosyl-cyclomaltoheptaose (beta-cyclodextrin, betaCD) were chemically synthesized by glucosylation of tris(2,3-di-O-acetyl)-tetrakis(2,3,6-tri-O-acetyl)-betaCDs with 2,3,4,6-tetra-O-benzyl-1-O-trichloroacetoimidoyl-alpha-D-glucopyranose in the presence of trifluoromethanesulfonic acid in dichloromethane, followed by debenzylation and deacetylation.The desired 61,6x,6y-tri-O-(alpha-D-glucopyranosyl)-betaCDs were isolated from each reaction mixture containing their configurational isomers by HPLC and characterized by 13C NMR spectroscopy.

Emerging targets for the treatment of idiopathic pulmonary fibrosis

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive lung disease characterized by scarring of the lung interstitium that likely occurs because of repetitive wounding of the alveolar epithelium, followed by incomplete healing of the injury. IPF is a disease of high, unmet medical need due to an exceptionally poor prognosis combined with a lack of effective treatment options capable of altering its progression. There is an urgent need for the development of novel pharmacological agents capable of providing significant efficacy while modifying the natural course of the disease. Herein, we describe emerging targets for the treatment of IPF and progress in the development of small-molecule modulators against them. Targets for which there is limited pharmacologic validation or against which only biologic modalities exist are excluded.

N-benzoylglycine/thiourea cooperative catalyzed stereoselective O-glycosidation: Activation of O-glycosyl trichloroacetimidate donors

A new practical utility for beta-stereoselective glycosylation via activation of O-glycosyl trichloroacetimidate donors using N-benzoylglycine/thiourea cooperative catalysis has been demonstrated. This method represents the first instance where amino acid derived N-benzoylglycine is used as a catalyst for O?glycosylation under mild reaction conditions at ambient temperature. NMR spectroscopy studies suggest that thiourea cocatalyst exhibit a cooperative behaviour that has a strong effect on the reaction rate, yield, and the beta-selectivity.

Silver Triflate. A Mild Alternative Catalyst for Glycosylation Conditions Using Trichloroacetimidates as Glycosyl Donors

Although trimethylsilyl triflate (TMSOTf) has been widely used to promote glycosyl trichloroacetimidates in oligosaccharide synthesis, silver triflate (AgOTf) was proved to be a mild and in some cases more efficient catalyst in TMSOTf-sensitive glycosylations. Migration and degradation in some specific coupling reactions can be reduced significantly under this alternative glycosylation condition.

Organocatalytic 1,4-conjugate addition of ascorbic acid to alpha,beta-unsaturated aldehydes: Bio-inspired total syntheses of leucodrin, leudrin and proposed structure of dilaspirolactone

The organocatalytic additions of ascorbic acid to various alpha,beta-unsaturated aldehydes via tandem 1,4-conjugate addition/hemiacetalization/hemiketalization were developed, which provided a rapid entry into the 5-5-5 spirodilactone cores of a family of ascorbylated natural products. Based on the described chemistry, total syntheses of leucodrin, leudrin and the proposed structure of dilaspirolactone were achieved. The Royal Society of Chemistry 2013.

Stereoelectronic effects determine oxacarbenium vs beta-sulfonium ion mediated glycosylations

Activation of a glycosyl donor protected with a 2-O-(S)-(phenylthiomethyl) benzyl ether chiral auxiliary results in the formation of an anomeric beta-sulfonium ion, which can be displaced with sugar alcohols to give corresponding alpha-glycosides. Sufficient deactivation of such glycosyl donors by electron-withdrawing protecting groups is, however, critical to avoid glycosylation of an oxacarbenium ion intermediate. The latter type of glycosylation pathway can also be suppressed by installing additional substituents in the chiral auxiliary.

A mild ligand-free iron-catalyzed liberation of alcohols from allylcarbonates

Different from most carbonates the allyloxy carbonyl protecting group can be cleaved under neutral conditions using metal catalysis. However, most of the catalysts employed to date are based upon precious metals. Herein we present two protocols for the mild Fe-catalyzed liberation of alcohols from allylcarbonates that are characterized by broad functional group tolerance and exclusive chemoselectivity.
