Napthalene-catalysed lithiation of carbamoyl and thiocarbamoyl chlorides under Barbier-type reaction conditions
Ramon, Diego J.,Yus, Miguel
, p. 13739 - 13750 (2007/10/03)
The reaction of different carbamoyl or thiocarbamoyl chlorides 1 with carbonyl compounds or imines 2 in the presence of an excess of lithium powder and a catalytic amount of naphthalene (3 mol %) in THF at -78°C leads, after hydrolysis with water, to the
Insertion of isocyanates, CO2, and ethylene carbonate into the Zr-C and Zr-N bonds of imine complexes. Construction of chiral centers like those in α-amino acids
Gately, Daniel A.,Norton, Jack R.,Goodson, Patricia A.
, p. 986 - 995 (2007/10/02)
In some cases zirconocene-imine complexes insert CO2; more generally they insert isocyanates and cyclic carbonates. Isocyanates can insert into either the Zr-C or the Zr-N bond; protonolysis of the zirconacycle resulting from Zr-C insertion giv
Anionic hetero[3,3] and [3,5][ rearrangements of hydroxylamine derivatives accompanied with N-O bond cleavage
Endo,Uchida,Hizatate,Shudo
, p. 1096 - 1105 (2007/10/02)
Aromatic and aliphatic N,O-divinylhydroxylamine systems generated in situ from hydroxylamine derivatives smoothly undergo [3,3] rearrangement. The base-catalyzed formation and rearrangement of enolates or dienolates of N-aryl-O-acylhydroxylamines, N,O-dia
