A new, highly stereoselective intramolecular cyclopropanation of vinylogous carbamates with carbenes in the presence of Cu(acac)2 as the catalyst has been developed for the construction of cyclopropapyrrolidinones. The ‘syn’ isomer of N-DAC can be converted to the ‘anti’ isomer by simple silica gel treatment. Regioselective cleavage of each of the cyclopropane bonds of these two acceptor substituted N-DACs led to a diverse array of azacycles.

A highly stereoselective synthesis of (-)-dihydrotetrabenazine has been accomplished using (R)-tert-butanesulfinamide as a chiral source. The synthesis involves the allylation of chiral N-sulfinyl imine followed by ring closure of the resulting secondary amide with a tethered halide and the Evans-Aldol reaction as key steps.

The first syntheses of 13,14-didehydroxyisogarcinol (6) and garcimultiflorone A (5) stereoisomers are reported in six steps from a commercially available phloroglucinol. Lewis acid-controlled, diastereoselective cationic oxycyclizations enabled asymmetric syntheses of (-)-6-epi-6 and (+)-30-epi-6. A similar strategy enabled production of the meso-dervied isomers (±)-6,30-epi-6 and (±)-6,30-epi-5. Finally, a convenient strategy for gram scale synthesis was developed utilizing diastereomer separation at a later stage in the synthesis that minimized the number of necessary synthetic operations to access all possible stereoisomers.

Two efficient routes for the total synthesis of (-)-epothilone B are reported. One strategy is based on ring-closing metathesis, and a second synthesis on a macrolactonization. The key fragments are available on large scale to provide sufficient material for biological tests. Thiazole fragment 4 was obtained by an improved route starting from (S)-malic acid. The first synthesis is based on our preceding paper. The critical trisubstituted double bond C12-13 in our second approach was constructed by a highly efficient Pd- mediated coupling reaction. Ring closure was achieved by macrolactonization.

A concise, flexible, and high yielding entry into the family of amphidinolide T macrolides, a series of cytotoxic natural products of marine origin, has been developed. All individual members, except amphidinolide T3 (3), derive from compound 39 as a common synthetic intermediate which is formed from three building blocks of similar size and complexity. The fragment coupling steps involve a highly diastereoselective SnCl4 mediated reaction of the furanosyl sulfone derivative 11 with the silyl enol ether 18 and a palladium-catalyzed Negishi type coupling reaction between the polyfunctional organozinc reagent derived from iodide 32a and the enantiopure acid chloride 24b. The 19-membered macrocyclic ring is then formed by a high yielding ring closing metathesis (RCM) reaction of diene 33 catalyzed by the “second generation” ruthenium carbene complex 34. The efficiency of the RCM transformation stems, to a large extent, from the conformational bias introduced by the syn-syn-configured stereotriad at C12-C14 of the substrate which constitutes a key design element of the synthesis plan. The use of Nysted’s reagent 38 in combination with TiCl4 was required for the olefination of the sterically hindered ketone group in 36, whereas more conventional alkene formations were unsuccessful for this elaboration. Finally, it is shown that the inversion of a single and seemingly remote stereocenter (C12) in one of the building blocks not only affects the efficiency and stereochemical outcome of the RCM step but also exerts a significant influence on the course of the acyl-Negishi reaction, allowing a radical manifold to compete with productive cross coupling.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms.In my other articles, you can also check out more blogs about 16251-45-9Application In Synthesis of (4S,5R)-4-Methyl-5-phenyloxazolidin-2-one
