Synthesis of penicillenol C1 and of a bis-azide analogue for photoaffinity labeling

Two diasteroisomers of the Penicillium metabolite penicillenol C 1 were synthesized for the first time by 3-acylation of an l-threonine-derived tetramic acid with enantiopure 2-methyloct-(6E)-enoic acids. The 5S,6R,9S isomer has NMR spectra and optical rotation identical with those of the natural compound. A bis-azide-tagged penicillenol analogue was also synthesized for photoaffinity labeling of target proteins. The photolysis of the bis-azide in the presence of methanol as a protein-mimicking nucleophile led to reaction only of the aryl azide, while leaving the benzyl azide available for pull-downs or the attachment of fluorescent tracers. As a proof of concept, the distribution of this bis-azide-tagged tetramic acid in living cells was visualized via a Staudinger ligation between the azide tag and a phosphane fluorophore.

An access to chiral beta-benzyl-gamma-butyrolactones and its application to the synthesis of enantiopure (+)-secoisolariciresinol, (-)-secoisolariciresinol, and (-)-enterolactone

Both enantiomers of secoisolariciresinol and enantiopure (-)-enterolactone were synthesized through a highly stereoselective convergent synthesis. An Evans diastereoselective alkylation followed by a substrate-induced diastereoselective -alkylation of the newly formed optically active beta-benzyl-gamma- butyrolactone gave the beta-beta? linkage of the target skeleton. The (S,S)- and (R,R)-enantiomers of secoisolariciresinol and (-)-enterolactone were obtained in 12-14% (11 steps) and 20% (7 steps) overall yield, respectively.

Dirhodium(II) tetrakis(carboxamidates) with chiral ligands. Structure and selectivity in catalytic metal-carbene transformations

Structure-selectivity comparisons are made between chiral dirhodium(II) tetrakis(methyl 2-oxopyrrolidine5-carboxylates), Rh2(5S-MEPY)4 and Rh2(5R-MEPY)4 (5), and dirhodium(II) tetrakis(4-benzyl-2- oxazolidinones), Rh2(4R-BNOX)4 and Rh2(4S-BNOX)4 (6), to ascertain and understand their relative effectiveness as catalysts for enantiocontrol in metal-carbene transformations. The syntheses, spectral characteristics, and X-ray structures for these dirhodium(II) compounds are reported. Each possesses two oxygen- and two nitrogen-donor atoms bound to each . octahedral rhodium with a cis orientation of the nitrogen ligands. The Rh2(MEPY)4 catalysts are significantly more effective than those of Rh2(BNOX)4 in providing a high level of enantiocontrol in intermolecular and intramolecular cyclopropanation reactions, in intermolecular cyclopropenation reactions, and in intramolecular C-H insertion reactions of diazoacetates and diazoacetamides, often reaching >90% enantiomeric excesses. Molecular mechanics calculations that were able to reproduce the X-ray structures of Rh2(5S-MEPY)4 and Rh2(4R-BNOX)4 have been employed to obtain the preferred conformation of the intermediate metal-carbene, but the absolute configurations of cyclopropanation products are opposite to those predicted from the preferred metal-carbene conformation. However, conformational energy minima of the styrene-carbene complex predict the observed enantiomer preference.

A ring-closing metathesis-based approach to the synthesis of (+)-tetrabenazine

A modular stereoselective synthesis of the vesicular monoamine transport inhibitors (+)-tetrabenazine ((+)-1) and (+)-alpha-dihydrotetrabenazine ((+)-2) has been developed. The approach is based on amine 4 and acid 5 as the key building blocks, which were elaborated into macrolactam 3 by amide coupling and a subsequent highly E-selective RCM reaction. Macrolactam 3 could be converted into tetrabenazine in three known steps.

Continuous Flow Synthesis of Carbonylated Heterocycles via Pd-Catalyzed Oxidative Carbonylation Using CO and O2 at Elevated Temperatures and Pressures

A continuous-flow Pd-catalyzed oxidative carbonylation protocol utilizing CO and O2 gas for the synthesis of carbonylated heterocycles is described. The optimization of temperature, pressure, CO/O2 ratio, catalyst loading, and reaction time resulted in process intensified conditions for this transformation. The optimized continuous flow conditions (120 C, 20 bar pressure, 24 min residence time) were used to prepare a number of benzoxazolone, 2-benzoxazolidinone, and other biologically and synthetically important five- and six-membered carbonylated heterocycles in good overall yield and purity (14 examples). The continuous-flow process enables the safe and scalable oxidative carbonylation using CO/O2 under elevated pressures and temperatures.

The preparation of tryptophan derivatives through the Lewis acid promoted substitution of aziridine carboxylates with indole was found to be accompanied by a ring-expansion reaction to generate an oxazolidinone byproduct. The ratio of tryptophan to oxazolidinone products can be optimized through a judicious choice of Lewis acid and N-protecting group.
