Catalytic enantioselective inverse electron demand hetero-diels-alder reaction with allylsilanes
Matsumura, Yuki,Suzuki, Takahiro,Sakakura, Akira,Ishihara, Kazuaki
supporting information, p. 6131 - 6134 (2014/06/23)
The first diastereo- and enantioselective inverse electron demand hetero-Diels-Alder reaction of β,γ-unsaturated α-ketoesters with allylsilanes is described. Chiral copper(II) catalysts successfully activate the β,γ-unsaturated α-ketoesters and promote the reaction with allylsilanes with excellent enantioselectivities. This process represents a new entry to chiral oxanes.
Stereoselective synthesis of functionalised triol units by SnCl4 promoted allylation of α-benzyloxyaldehydes: Crucial role of the stoichiometry of the Lewis acid
Dubost, Christophe,Leroy, Bernard,Markó, Istvan E.,Tinant, Bernard,Declercq, Jean-Paul,Bryans, Justin

Enantiomerically pure syn-anti and syn-syn configured triol units are efficiently synthesized by the SnCl4 mediated allylation of chiral α-benzyloxyaldehydes with the uniquely functionalised allylstannane 9. Remarkably, the stereochemistry of t
Microbial deracemization of α-substituted carboxylic acids: Substrate specificity and mechanistic investigation
Kato, Dai-Ichiro,Mitsuda, Satoshi,Ohta, Hiromichi
, p. 7234 - 7242 (2007/10/03)
A new enzymatic method for the preparation of optically active α-substituted carboxylic acids is reported. This technique is called deracemization reaction, which provides us with a route to obtain the enantiomerically pure compounds, theoretically in 100% yield starting from the racemic mixture. This means that the synthesis of a racemate is almost equal to the synthesis of the optically active compound, and this concept is entirely different from the commonly accepted one in the asymmetric synthesis. Using the growing cell system of Nocardia diaphanozonaria JCM3208, racemates of 2-aryl- and 2-aryloxypropanoic acid are deracemized smoothly and (R)-form-enriched products are recovered in high chemical yield (>50%). In addition, using optically active starting compounds and deuterated derivatives as well as inhibitors, we have disclosed the fact that a new type of enzyme takes part in this biotransformation, and that the reaction proceeds probably via the same mechanism as that in rat liver.

(Equation presented) In this communication we demonstrate that Prins cyclization reactions occur under very mild conditions when cyclic α,β-unsaturated acetals are employed as oxocarbenium ion progenitors and allylsilanes are used as nucleophiles. Cycliza

Almond oxynitrilase-catalyzed transformation of aldehydes is strongly influenced by naphthyl and alkoxy substituents
Roda, Gabriella,Riva, Sergio,Danieli, Bruno
, p. 3939 - 3949 (2007/10/03)
Different α- and β-substituted aldehydes have been submitted to the catalytic action of almond oxynitrilase (PaHNL), in order to explore the influence of a stereocenter already present in the substrate on the selectivity of this enzyme. The results indicate that naphthyl and alkoxy substituents in the α- and also in the β-position to the aldehyde group significantly influence the stereochemical outcome of the PaHNL-catalyzed transformation.
