Visible-Light-Induced ortho-Selective Migration on Pyridyl Ring: Trifluoromethylative Pyridylation of Unactivated Alkenes

The photocatalyzed ortho-selective migration on a pyridyl ring has been achieved for the site-selective trifluoromethylative pyridylation of unactivated alkenes. The overall process is initiated by the selective addition of a CF3 radical to the alkene to provide a nucleophilic alkyl radical intermediate, which enables an intramolecular endo addition exclusively to the ortho-position of the pyridinium salt. Both secondary and tertiary alkyl radicals are well-suited for addition to the C2-position of pyridinium salts to ultimately provide synthetically valuable C2-fluoroalkyl functionalized pyridines. Moreover, the method was successfully applied to the reaction with P-centered radicals. The utility of this transformation was further demonstrated by the late-stage functionalization of complex bioactive molecules.

A dual-catalysis approach to the asymmetric steglich rearrangement and catalytic enantioselective addition of O-acylated azlactones to isoquinolines

A dual-catalysis approach, namely the combination of an achiral nucleophilic catalyst and a chiral anion-binding catalyst, was applied to the Steglich rearrangement to provide alpha,alpha-disubstituted amino acid derivatives in a highly enantioselective fashion. Replacement of the nucleophilic co-catalyst for isoquinoline resulted in a divergent reaction pathway and an unprecedented transformation of O-acylated azlactones. This strategy provided highly substituted alpha,beta-diamino acid derivatives with excellent levels of stereocontrol.

The Synthesis of Indolizidine and Quinolizidine Ring Systems by Free Radical Cyclization of 4-Aza-6-methoxycarbonyl-5-hexenyl Radicals

The formation of bicyclic amines by the intramolecular cyclization of 4-aza-6-methoxycarbonyl-5-hexenyl radicals is described.The direct attachment of a nitrogen atom to the double bond changes the electronic nature of the alkene such that the cyclization is less efficient than the all carbon analogue or the other aza-substituted 5-hexenyl cyclizations.The reaction has been used in a short, convenient synthesis of a variety of indolizidines from methyl nicotinate.In addition, the cyclization was used as the key step in a short synthesis of (+/-)-epilupinine from methyl nicotinate.

Tyrosine kinase inhibitors. 5. Synthesis and structure-activity relationships for 4-[(phenylmethyl)amino]- and 4-(phenylamino)quinazolines as potent adenosine 5′-triphosphate binding site inhibitors of the tyrosine kinase domain of the epidermal growth factor receptor

A series of 4-substituted quinazolines and related compounds have been prepared and evaluated for their ability to inhibit the tyrosine kinase activity of the epidermal growth factor receptor on a phospholipase C-gamma1- derived substrate. The results show a narrow structure-activity relationship (SAR) for the basic ring system, with quinazoline being the preferred chromophore and benzylamino and anilino the preferred side chains. In the 4- anilino series, substitution on the 3-position of the phenyl ring with small lipophilic electron-withdrawing groups provided analogues with enhanced potency. Two series of compounds [4-(phenylmethyl)amino and 4-(3- bromophenyl)amino] were studied to determine SARs for quinazoline substituents. In the more active 4-(3-bromophenyl)amino series, electron- donating groups (NH2, OMe) at the 6- or 7-position increased activity, in a pattern consistent with a requirement for high electron density in the vicinity of the 8-position of the quinazoline ring. The 6,7-dimethoxy derivatives were the most effective in both series, with the 4-(3- bromophenyl)amino derivative (3) having an IC50 of 0.029 nM, making it by far the most potent reported inhibitor of the tyrosine kinase activity of the epidermal growth factor receptor enzyme.

An efficient synthesis of the potent dopamine D1 agonist dinapsoline by construction and selective reduction of 2?-azadimethoxybenzanthrone

8,9-Dihydroxy-2,3,7,11b-tetrahydro-1H-naphth[1,2,3-de]isoquinoline (dinapsoline, 1) is a potent dopamine D1 receptor agonist with potential antiparkinsonian activity. A new synthesis was developed with the fully aromatic compound 2 as the key intermediate. The synthesis herein described is suitable for a larger scale preparation of dinapsoline compared to the previously known methods. Furthermore, the unproductive protection/deprotection step of the nitrogen is circumvented by maintaining a high oxidation state of the isoquinoline moiety throughout the synthesis. The construction of the framework was accomplished by Friedel-Crafts acylation and a Suzuki cross-coupling reaction between the commercially available 4-bromoisoquinoline and aryl boronic acid 5, the latter demanding the transformation of the lithiation-directing amide back to a carboxylic acid functionality. The selective reduction was carried out stepwise with sodium borohydride and sodium cyanoborohydride. The new synthesis is high yielding and reduces the number of transformations in the previously reported methods.
