چکیده
The enantioselective synthesis of 7-epi-incarvilline for formal syntheses of (-)-incarvilline, (+)-incarvine C, and (-)-incarvillateine is described. The key features of our synthesis involve (1) stereoselective construction of the optically active bicyclic lactone utilizing Pd(0)-catalyzed allylic alkylation, (2) efficient transformation of the bridged bicyclic lactone to the key bicyclic lactam skeleton, and (3) stereoselective elaborations of two stereocenters via a substrate-controlled catalytic hydrogenation and a 1,4-addition.

Stereoselective synthesis and biological evaluation of D-fagomine, D-3-epi-fagomine and D-3,4-epi-fagomine analogs from D-glyceraldehyde acetonide as a common building block.
The stereoselective synthesis of D-fagomine, D-3-epi-fagomine, and D-3-epi-fagomine analogs starting from readily available D-glyceraldehyde acetonide has been achieved. The synthesis involves diastereoselective anti-vinylation of its homoallylimine, ring-closing metathesis, and stereoselective epoxidation followed by regioselective ring-opening or stereoselective dihydroxylation. The lack of a...

The first total synthesis of (+)-giganin and its unnatural diastereoisomer (+)-C10-epi-giganin has been completed in a total of 13 linear steps, and 7 % and 8 % overall yield, respectively (see scheme; (-)-sp= (-)-sparteine, (+)-sps=(+)-sparteine surrogate). Lithiation-borylation methodology has been successfully applied in the key step, to couple together advanced intermediates with very high ...
متن کاملSynthesis of the C4-epi-lomaiviticin B core reveals subtle stereoelectronic effects.
An efficient synthesis of the C4-epi-lomaiviticin B core is reported. The synthesis features a diastereoselective anionic formal furan Diels-Alder reaction and a stereoselective oxidative enolate dimerization. During the investigation, subtle yet critical stereoelectronic effects imparted by the C4-stereocenter were observed.

A chiral aziridine was utilized for the synthesis of the anti-bacterial natural amino acid L-(+)-furanomycin, and its analogues including 5'-epi-furanomycin and norfuranomycin. Key steps of this synthesis are the stereoselective Pd-catalyzed etherification for diallyl ethers and ring closing metathesis.
