Transition metal-catalyzed synthesis and reactivity of N-alkenyl aziridines.
Org. Lett. 6th ed., 7 , 1161-1164, (2005) [reaction: see text] Straightforward methods for palladium-catalyzed alkenylation of aziridines with alkenyl halides and copper-catalyzed alkenylation of aziridines with alkenyl boronic acids have been developed. This methodology offers attractive alternative... |

Stereoselective isomerisation of N-allyl aziridines into geometrically stable Z enamines by using rhodium hydride catalysis.
Chemistry 3rd ed., 14 , 886-894, (2008) In the presence of rhodium(I) hydride catalysts, tertiary N-allylamines are known to isomerise into E enamines. In contrast, we have recently found that N-allylaziridines isomerise to form Z enamines. On the basis of literature data, the most likely mechanism... |

Kinetic resolution of axially chiral 2,2'-dihydroxy-1,1'-biaryls by palladium-catalyzed alcoholysis.
J. Am. Chem. Soc. 30th ed., 127 , 10474-10475, (2005) Palladium-diamine complexes catalyzed kinetic resolution of axially chiral 2,2'-dihydroxy-1,1'-biaryls by alcoholysis of vinyl ethers. The reaction proceeded with high selectivity for various kinds of biaryls. This process is applicable to not only binaphthol... |

Efforts toward distorted spiropentanes.
J. Org. Chem. 21th ed., 75 , 7494-7497, (2010) Tetravinylbenzene 4 was prepared in nearly quantitative yield from commercially available tetrabromobenzene; the improved, one-step procedure now employs Suzuki-Miyaura cross-coupling conditions. Intermolecular cyclopropanation of 4 with dibromocarbene gave a... |

Structure based design, synthesis and SAR of cyclic hydroxyethylamine (HEA) BACE-1 inhibitors.
Bioorg. Med. Chem. Lett. 7th ed., 21 , 1942-1947, (2011) This Letter describes the de novo design of non-peptidic hydroxyethylamine (HEA) inhibitors of BACE-1 by elimination of P-gp contributing amide attachments. The predicted binding mode of the novel cyclic sulfone HEA core template was confirmed in a X-ray co-c... |

Stereoselective synthesis of substituted 1,3-oxazolidines via Pd-catalyzed carboamination reactions of O-vinyl-1,2-amino alcohols.
Org. Lett. 17th ed., 13 , 4728-4731, (2011) The stereoselective synthesis of 2,4- and 2,5-disubstituted 1,3-oxazolidines is accomplished via Pd-catalyzed carboamination of O-vinyl-1,2-amino alcohol derivatives. The transformations generate cis-disubstituted products with good to excellent diastereosele... |

Acids direct 2-styrylcyclobutanone into two distinctly different reaction pathways.
Org. Lett. 10th ed., 7 , 2059-2061, (2005) Two structurally distinct carbocycles were selectively obtained by the reactions of 2-(o-styryl)cyclobutanones promoted by ytterbium salts. Treatment of the cyclobutanones with YbCl(3) in 1,4-dioxane at 100 degrees C afforded 2-(2-chloroethyl)naphthalenes. On... |
