Enantioselective Synthesis of Renieramide.

ChemInform, 2004
A highly chemo- and enantioselective PTC alkylation has been developed that allows rapid access to orthogonally protected (S,S)-isodityrosine. Utility of this material in the construction of isodityrosine-containing cyclic peptides is demonstrated by synthesis of the natural product renieramide.

Enantioselective Synthesis of (−)-Pentalenene

Organic Letters, 2007
A short, enantioselective synthesis of (-)-pentalenene is described. Catalytic enantioselective cyclopropenation with (R,R)-Rh2(OAc)(DPTI)3 was used to set the absolute stereochemistry, and an intramolecular Pauson-Khand reaction of the resulting cyclopropenyne was used to establish the quaternary center.

Enantioselective Synthesis of Silacyclopentanes

Angewandte Chemie, 2016
AbstractA variety of functionalized silacyclopentanes were synthesized by highly enantioselective β‐eliminations of silacyclopentene oxides followed by stereospecific transformations. The reaction mechanism of the β‐elimination was elucidated by DFT calculations.

Enantioselective synthesis of levomilnacipran

Chemical Communications, 2012
A novel approach for the asymmetric synthesis of the active (1S,2R)-enantiomer of the antidepressant milnacipran is reported. The two stereogenic centers borne by the cyclopropane ring were sequentially installed starting from phenylacetic acid.

Enantioselective Synthesis of Phenylpropanetriols

Synthetic Communications, 1998
Abstract The four stereomer 1-(4-hydroxy-3-methoxy)-phenyl-1,2,3-propanetriols were obtained in about 30% yields starting from ferulic acid by a synthesis based on osmium catalyzed asymmetric dihydroxylation.

Enantioselective Synthesis of Xanthatin

Chemistry – A European Journal, 2014
AbstractThe enantioselective synthesis of cytostatic and antibiotic xanthatin (1 a) is reported. As a key intermediate, a bicyclic compound 2 was identified, which can be readily synthesized from methyl‐2‐furoic acid in diastereo‐ and enantiomerically pure form.

Enantioselective Synthesis of Silanol

Journal of the American Chemical Society, 2008
An enantioselective nucleophilic substitution reaction of achiral dialkoxysilane has been developed. The reaction proceeds with efficient stereocontrol on the silicon chirality center to give the enantioenriched silyl ether, which can be converted to the silanol without loss of enantiopurity.
