Highly Chemoselective Allylation of Aldehydes in the Presence of Ketones
Kim, Sunggak,Kim, Sung Hoon
, p. 3723 - 3724 (1995)
Highly chemoselective allylationn of aldehydes in the presence of ketones has been achieved by preferential in situ conversion of aldehydes into 1-silyloxysulfonium salts and subsequent displacement with ally;tributyltin.
Total Synthesis of Diocollettines A via an Acid-Promoted Oxa-Michael-Aldol-Acetalization Cascade
Kawamoto, Misaki,Sato, Shuntaro,Enomoto, Masaru,Ogura, Yusuke,Kuwahara, Shigefumi
, p. 10099 - 10101 (2019)
A diastereo- and enantioselective total synthesis of diocollettines A with an unusual oxygen-containing tricyclic ring system has been achieved in 63% overall yield from commercially available 3-phenylpropanal via four steps. The key feature of the presen
A Grignard-Type Addition of Allyl Unit to Carbonyl Compounds Containing a Carboxyl Group by Using BiCl3-Zn(0)-Allyl Bromide
Wada, Makoto,Honna, Munckazu,Kuramoto, Yoshihiro,Miyoshi, Norikazu
, p. 2265 - 2267 (1997)
In the presence of BiCl3-Zn(0), nearly equimolar amounts of allyl bromide reacted with carbonyl compounds containing a carboxyl group to afford the corresponding homoallylic alcohols having a carboxyl group or the intramolecular dehydrated lact
Cr(salen)-catalyzed asymmetric addition of allylstannane to aldehydes
Shimada, Yuya,Katsuki, Tsutomu
, p. 786 - 787 (2005)
Cr(salen) complex 3 was found to be an efficient catalyst for asymmetric addition of allyltributylstannane to non-branched aliphatic aldehydes, giving the corresponding homoallylic alcohols in a highly enantioselective manner. For example, its addition to

A visible-light-induced dioxygenation of β,γ-unsaturated oximes for the synthesis of diverse useful isoxazolines bearing a hydroxyl moiety was developed by employing graphitic carbon nitride (g-C3N4) as a heterogeneous photocatalyst under an air atmosphere. Noted that, the eminent advantages of this metal-free protocol include step economy, easy operation, a recyclable photocatalyst, external reductant-/oxidant-free and mild reaction conditions. Additionally, mechanistic studies indicated hydroxyl radical was generated under the photocatalysis of g-C3N4.

An organocatalytic asymmetric synthesis of cyclic acetal with spirooxindole skeleton has been developed via a domino reaction between isatin and γ-hydroxy enones. Bifunctional squaramide catalyst with adamantyl motif was found to be the most effective for the cascade reaction. With 10 mol% of the catalyst, the desired products were obtained in 1.8:1 to 9:1 diastereo- and 86% to >99% enantioselectivities from a range of substituted isatins and γ-hydroxy enones.
