Rhodium(III)-Catalyzed C-H Alkynylation of Ferrocenes with Hypervalent Iodine Reagents

Rapid access to mono- or dialkynylation of ferrocene with ethynylbenziodoxolones as the alkynylation reagents was achieved via rhodium-catalyzed direct C-H bond functionalization at room temperature. Mono- and dialkynylation were easily modulated by varying the sterical volume of the directing group, such as pyridine and isoquinoline, and amount of hypervalent iodine reagents. A wide range of ferrocene-based alkynylation products could be obtained in up to 94% yield, and a gram-scale reaction also proceeded smoothly with high efficiency.

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.

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.
