Chemical transformations that install heteroatoms into C?H bonds are of significant interest because they streamline the construction of value-added small molecules. Direct C?H oxyfunctionalization, or the one step conversion of a C?H bond to a C?O bond, could be a highly enabling transformation due to the prevalence of the resulting enantioenriched alcohols in pharmaceuticals and natural products,. Here we report a single-flask photoredox/enzymatic process for direct C?H hydroxylation that proceeds with broad reactivity, chemoselectivity and enantioselectivity. This unified strategy advances general photoredox and enzymatic catalysis synergy and enables chemoenzymatic processes for powerful and selective oxidative transformations.
Convergent routes to substituted naphthylamides
Tran, Ngoc Diem My,Zard, Samir Z.
, p. 3251 - 3264 (2014/05/06)
Practical, convergent routes to variously substituted 1- and 2-naphthylamides have been developed. They exploit the ability of xanthates to undergo both intermolecular radical additions to vinyl pivalate and intramolecular radical cyclisations to aromatic

(Chemical Equation Presented) A family of tunable precatalysts [NH 2Et2][{Ru(4,4′-BINAP)Cl}2(μ-Cl) 3] was synthesized and used for highly enantioselective hydrogenation of phthalimide-protected amino ketones and
Highly Enantioselective Asymmetric Hydrogenation of α-Phthalimide Ketone: An Efficient Entry to Enantiomerically Pure Amino Alcohols
Lei, Aiwen,Wu, Shulin,He, Minsheng,Zhang, Xumu
, p. 1626 - 1627 (2007/10/03)
A new type of α-phthalimide ketones was hydrogenated in excellent enantioselectivity by using a Ru-(C3-TunePhos) complex as the catalyst. Up to 10000 turnovers have been achieved in more than 99% ee in the hydrogenation reaction. A dynamic kinetic resolution study for the synthesis of threonine was performed, and high anti selectivity (>97:3) was observed for the first time. An efficient method to synthesize enantiomerically pure amino alcohols has been developed. Copyright

Compounds represented by Formula (I): or pharmaceutically acceptable salts thereof, are inhibitors of glycogen phosphorylase and are useful in the prophylactic or therapeutic treatment of diabetes, hyperglycemia, hypercholesterolemia, hyperinsulinemia, hyperlipidemia, hypertension, atherosclerosis or tissue ischemia e.g. myocardial ischemia, and as cardioprotectants.
A convenient one-pot synthesis of 4-amino-3-arylpyrazoles from α- phthaloylaminoacetophenones
Chen, Chen,Wilcoxen, Keith,McCarthy, James R.

Condensation of α-phthaloylaminoacetophenones 1a-c with N,N- dimethylformamide dimethyl acetal afforded the novel enamines 3a-c. Cyclization of 3 with hydrazine, alkylhydrazine or phenylhydrazine salts (4a- d) gave 4-phthaloylamino-3-arylpyrazoles 7-9 in
Potential GABAB Receptor Antagonists. VII. The Synthesis of 2-(4-Chlorophenyl)-3-nitropropan-1-amine and Related Analogues of Baclofen

, p. 1441 - 1452 (2007/10/02)
3-Nitro-2-phenylpropan-1-amine and 2-(4-chlorophenyl)-3-nitropropan-1-amine have been synthesized by the addition of nitrous acid to the corresponding trifluoroacetylaminomethylstyrenes followed by reduction of the double bond with sodium borohydride.A more general and efficient route involves the Michael addition of nitroalkane anions to methyl cinnamates followed by Curtius degradation of the corresponding acids. 2-(4-Chlorophenyl)-3-nitropropan-1-amine is a specific agonist of GABA and the GABAB receptor, with about half the activity of racemic baclofen at the isolated guinea pig ileum.Methylation or dimethylation at C3 decreases activity markedly.
