Justus Freiherr von Liebig [2] 12 May — 18 April [3] was a German scientist who made major contributions to agricultural and biological chemistry , and is considered one of the principal founders of organic chemistry. He popularized an earlier invention for condensing vapors, which came to be known as the Liebig condenser. At the age of 13, Liebig lived through the year without a summer , when the majority of food crops in the Northern Hemisphere were destroyed by a volcanic winter. Due in part to Liebig's innovations in fertilizers and agriculture, the famine became known as "the last great subsistence crisis in the Western world". Liebig attended grammar school at the Ludwig-Georgs-Gymnasium in Darmstadt, from the ages of 8 to He worked with his father for the next two years, [9] : 7—8 then attended the University of Bonn , studying under Karl Wilhelm Gottlob Kastner , his father's business associate. When Kastner moved to the University of Erlangen , Liebig followed him. Liebig left Erlangen in March , in part because of his involvement with the radical Korps Rhenania a nationalist student organization , but also because of his hopes for more advanced chemical studies. The circumstances are clouded by possible scandal.

Biaryl atropisomers are key structural components in chiral ligands, chiral functional materials, natural products, and bioactive compounds, and their asymmetric syntheses have been reported by many groups. In contrast, although The Chemical Compounds Of Synthetic Fertilizer scientific community has long been aware of atropisomers due to rotational restriction around N—C bonds, they have attracted scant attention and have remained an unexplored research area. In particular, their catalytic asymmetric synthesis and the synthetic applications were unknown until recently. This Account describes studies conducted by our group on the catalytic enantioselective syntheses of N—C axially chiral compounds and their applications in asymmetric reactions.

These reactions were the first highly enantioselective syntheses of N—C axially chiral compounds with a chiral catalyst.

Since the publication of these reactions, N—C axially chiral compounds Snthetic been widely accepted as new target molecules for catalytic asymmetric reactions. Furthermore, chiral-Pd-catalyzed intramolecular N -arylations were applied to the enantioselective syntheses of N—C axially chiral quinolineone and phenanthridinone derivatives. We also succeeded in the enantioselective syntheses of various N—C axially chiral compounds using other chiral Pd-catalyzed reactions. That is, optically active N—C axially chiral N - 2- tert -butylphenyl indoles, 3- 2-bromophenyl quinazolinones, and N - 2- tert -butylphenyl sulfonamides were obtained through chiral Pd-catalyzed 5- endo -hydroaminocyclization, monohydrodebromination reductive asymmetric desymmetrizationand Tsuji-Trost N -allylation, respectively.

The study of the catalytic asymmetric synthesis of axially chiral indoles has contributed to the development of not only N—C axially chiral The Chemical Compounds Of Synthetic Fertilizer but also the chemistry of axially chiral indoles.

Subsequently, the catalytic asymmetric syntheses of various indole Feryilizer bearing a C—C chiral axis as well as an N—C chiral axis have been reported by many groups. Moreover, axially chiral quinazlolinone derivatives, which were obtained through chiral Pd-catalyzed asymmetric desymmetrization, are pharmaceutically attractive compounds; for example, 2-methyl 2-bromophenyl quinazolinone product is a mebroqualone possessing GABA agonist activity. Most of the N—C axially chiral products have satisfactory rotational stability for synthetic applications, and their synthetic utility was also demonstrated through Syntheyic to chiral enolate chemistry. That is, the reaction of various alkyl halides with the enolate prepared from the optically active anilide, lactam, and quinazolinone products proceeded with high diastereoselectivity by asymmetric induction due to the N—C axial chirality.

At the present time, N—C axially chiral chemistry has become a popular research area, especially in synthetic organic chemistry, and original papers on the catalytic asymmetric syntheses of various N—C axially chiral compounds and their synthetic applications have been published.
