Abstract:

We have studied for a long time the reaction of quinone acetal type compounds, such as quinone monoacetals, quinone O,S-acetals, and iminoquinone monoacetals, and have reported the regioselective introduction of various nucleophiles. Quinone monoacetals show various types of reactivities toward nucleophiles due to their unique structures. In this study, we found that aromatic and alkene nucleophiles can be regioselectively introduced into the α-position of the carbonyl group on quinone monoacetals by specific activation of the acetal moiety. These reactions enabled the metal-free synthesis of

A Fischer indole synthesis with a cis-configurated octahydroisobenzofuran-6-one yielded exclusively a furo[3,4-c]carbazole derivative as the product of a regioselective angular annulation reaction.

When submitting a mixture of cis- and trans-octahydroisoindole derivatives to Fischer and Friedländer syntheses, the trans-starting material gave regioselectively linear annulation products, i. e. pyrrolo[3,4-b]carbazole an

Abstract:

A highly regioselective synthesis of chlorohydrins by chlorinative cleavage of unsymmetrical epoxides utilizing dimethoxyboron chloride is described. Except for styrene oxide, all the terminal epoxides were regioselectively cleaved following a predominantly SN2-type reaction pathway favouring the formation of primary chlorides. In the case of styrene oxide, a benzylic epoxide, (MeO)2BCl transfers the chlorine at the benzylic position, by following an apparent SN1-type mechanism.

Abstract:

The chemo- and regioselective functionalization of fullerenes is a long-standing problem of organic synthesis. Over the past five years, this fundamental challenge has gained technological relevance, because studies on single bis-adduct isomers in new-generation solar cells have demonstrated that the widespread use of isomer mixtures leads to suboptimal power conversion efficiencies. Herein, we review recent work on supramolecular approaches for achieving chemo- and regioselective syntheses of multiply functionalized derivatives of C60.

The formation of the l-isomer was confirmed through measurement of the optical activity. The current strategy paves the way for the construction of diverse analogues of (–)-herdmanine D for drug development.

Abstract:

We reported palladium-catalyzed regioselective [3+2] cycloadditions of α,β-unsaturated imines with vinylethylene carbonates, providing the desired oxazolidines in moderate-to-high yields. This reaction provides a facile route for the highly regioselective synthesis of functional oxazolidines. The synthetic utility of the current method was also demonstrated by a gram-scale reaction.

Abstract:

Regioselective functionalization of core per-substituted boron dipyrromethenes (BODIPYs) has been achieved efficiently based on tetrabromoBODIPY, which affords a series of dibenzofuran-fused chromophores, via a regioselective nucleophilic substitution reaction followed by direct palladium-catalyzed two-fold intramolecular ring fusion. These rigid dibenzofuran-fused BODIPYs showed impressive photophysical properties such as clearly red-shifted absorption and emission bands, enhanced absorption coefficients upon and intense fluorescence (close to unity).

Abstract:

We report the synthesis of perhalogenated BODIPYs and investigate the regioselective functionalization of a perhalogenated BODIPY using Pd(0)-catalyzed Stille cross-coupling reactions. Further reaction at the boron atom produces nona-functionalized BODIPYs.

Abstract:

A highly regioselective reaction between allylzinc bromide reagents and α,β-unsaturated oxime ethers for the one-step synthesis of the homoallylic amines is reported. This process is a regioselective 1,2-addition reaction providing a new γ-position with carbon–carbon bond formation. Furthermore, the reaction substrates are widely applicable and can be produced in a high yield.
