Mannich Reaction of Secondary Benzylzinc Reagents: Synthesis of α,β‐Disubstituted β‐Arylethylamines

Asian Journal of Organic Chemistry, EarlyView.
The organometallic Mannich multicomponent reaction (MCR) of secondary benzylzinc reagents is described. The final α,β‐disubstituted β‐arylethylamines are obtained in generally high yields. The reaction is however characterized by a general lack of diastereoselectivity. A possible explanation is provided.

Synthesis of (‐)‐8a epi‐Lentiginosine via Tsuji‐Trost Reaction of d‐Glucose‐Derived Allylic Alcohols and Crystal Structure Analysis

Asian Journal of Organic Chemistry, Accepted Article.
An indolizidine alkaloid, (‐)‐8a‐epi‐lentiginosine was synthesized from d‐glucose using the Pd‐BiPhePhos catalyzed intramolecular Tsuji‐Trost reaction of non‐derivatized allylic alcohol as a key construction of the hydroxylated pyrrolidine ring to give the desired product in good yield and high diasterespecificity stereospecificity (dr = 97:3).

meso‐Free Porphyrinoids

Asian Journal of Organic Chemistry, EarlyView.
meso‐Free porphyrinoids are recognized as a versatile platform for further functionalization and oligomerization. The synthesis and characteristic features of such meso‐free porphyrinoids are reviewed. Abstract meso‐Unsubstituted (meso‐free) porphyrins have been an effective platform for creating versatile peripherally functionalized porphyrins and ...

Thiophene Containing Polycyclic Aromatic Hydrocarbon Monkey Saddles

Asian Journal of Organic Chemistry, Accepted Article.
Negatively curved chiral polycyclic aromatic hydrocarbons (PAHs) gained a lot of interest in research over the past years. By replacing phenyl against thiophene units in a monkey saddle shaped PAH, it was possible to further tune the photophysical and electrochemical properties as well as influence the racemization barrier of these three‐dimensional ...

Sugar‐sensing swodkoreceptors and swodkocrine signaling

Animal Models and Experimental Medicine, EarlyView.
Sugar‐sensing swodkoreceptors that trigger swodkocrine signaling. Abstract Sugars are one of the major metabolites and are essential for nucleic acid synthesis and energy production. In addition, sugars can act as signaling molecules. To study sugar signaling at the systemic level, there is an urgent need to systematically identify sugar‐sensing ...
