Synthesis of N-(tert-butoxycarbonyl)-N,O-isopropylidene serinal from serine methyl ester by a reduction-oxidation sequence

The title aldehyde is prepared by LiAlH4 reduction of the corresponding serine derived methyl ester to the alcohol and Swern oxidation of the latter. The aldehyde is obtained in 94 % yield and 96-98 % enantiomeric purity. This method avoids some problems encountered in the synthesis of the same aldehyde by direct controlled DIBAL reduction of the ester.

Design and optimization of new phosphine oxazoline ligands via high- throughput catalyst screening

This paper uses the phosphine oxazoline ligands 1 and an allylation transformation (reaction 1) to illustrate the value of divergent ligand syntheses and high-throughput screening in catalyst discovery and optimization. Thus, a diverse set of ligands 1 (Table 1) was prepared via a divergent synthesis involving the pivotal intermediate, phosphine-substituted amino alcohol 7 (Scheme 1). Single-crystal X-my crystallographic data was obtained for a nickel complex 8 (Figure 3) of the phenyl-substituted ligand 1i. This analysis illustrated some structural features of the ligand systems 1 that may be conducive to asymmetric catalysis. High-throughput screens were then used to correlate the ligand 1 R-substituents with asymmetric induction in the allylation reaction 1, and it emerged that the pseudo-spherical adamantyl substituent was superior to other R-substituents. Other parameters in the catalyst systems were also varied, sometimes in ‘two-dimensional’ screens. No pronounced solvent effects were identified. Abstraction of chloride was shown to be detrimental, whereas addition of chloride provided no advantages. One of the most critical of all the variables probed was, rather surprisingly, the effect of ligand-to-metal ratio; enantioselectivities dropped sharply and eventually reversed when this ratio was increased above 1:1. These observations were rationalized in terms of a chelated complex A and a nonchelated one B (Scheme 3). The implications of these results for high-throughput screening of catalyst systems in general, and for ligands 1 in particular, are discussed.

A novel way to chiral 2-oxazolidinones: selenium-catalyzed cyclocarbonylation of 2-aminoethanols

Selenium-catalyzed cyclocarbonylation of 2-aminoethanols with CO under atmospheric pressure at 30 C afforded 2-oxazolidinones in excellent yields without any other co-catalyst. The method was then applied to the syntheses of chiral 2-oxazolidinones and no racemization was detected.

Chiral Bidentate Boryl Ligand Enabled Iridium-Catalyzed Asymmetric C(sp2)-H Borylation of Diarylmethylamines

Optically active organoboronic acids and their derivatives are an important family of target compounds in organic chemistry, catalysis, and medicinal chemistry. Yet there are rare asymmetric catalytic examples reported for the synthesis of these compounds via atom and step economic ways. Herein, we report a chelate-directed iridium-catalyzed asymmetric C(sp2)-H borylation of aromatic C-H bonds directed by free amine groups. The success of these transformations relies on a novel family of chiral bidentate boryl ligands (L). They can be synthesized straightforwardly in three steps starting from readily available (S,S)-1,2-diphenyl-1,2-ethanediamie ((S,S)-DPEN). The Ir-catalyzed C(sp2)-H borylation comprises two parts. The first part is desymmetrization of prochiral diarylmethylamines. In the presence of L3/Ir, a vast array of corresponding borylated products were obtained with high regioselectivity and good to excellent enantioselectivities (26 examples, up to 96% ee). The second part, kinetic resolution of racemic diarylmethylamines, was also conducted. Good selectivity values (up to 68%, 11 examples) were obtained when L8 was used. We also demonstrated the synthetic utility of the current method on gram-scale reaction for several transformations. The C-B bonds of borylated products could be converted to a variety of functionalities including C-O, C-C, C-C, C-Br, and C-P bonds. Finally, we performed DFT calculations of desymmetrization to understand its reaction pathways.

Oxidative degradation of amines using a closed batch system

Oxidative degradation experiments on five amines and two amino acids were performed in a new closed setup at atmospheric pressure. For most of the amines/amino acids significant degradation was not present under these conditions, except for MEA and MMEA. The degradation compounds found seem to follow the same patterns as described in literature. Volatile compounds as ammonia and alkylamine play an important role in understanding the initial degradation mechanisms. For MMEA, methylamine and ammonia were found in the same order of magnitude. Oxygen stochiometry of the degradation compounds could not be explained by initial air in the system. Oxygen in some of the degradation compounds could come from oxygen diffusing into the system as seen from proposed model and/or water reacting with iminium giving aldehyde and amine/ammonia. Temperature and dissolved metal seemed to influence oxygen and degradation rate for the MEA experiments.
