A highly chemoselective Mukaiyama aldol reaction of saturated aldehyde over unsaturated aldehyde with enol tris(2,6-diphenylbenzyl)silyl ether
Seiji Shirakawa,Keiji Maruoka +1 more
TL;DR: In this paper, an exceedingly high chemoselective Mukaiyama aldol reaction of saturated aldehydes in the presence of unsaturated aldehyde (benzaldehyde and α,β-enals) has been realized for the first time by using the structurally unique enol tris(2,6-diphenylbenzyl)silyl ether under the influence of BF3·OEt2 as a Lewis acid.
Journal ArticleDOI
Regioselective Robinson Annulation Realized by the Combined Use of Lithium Enolates and Aluminum Tris(2,6-diphenylphenoxide) (ATPH)
TL;DR: In this paper, the addition of lithium enolates derived from ketones to a variety of α,β-unsaturated ketones was realized in the presence of aluminum tris(2,6-diphenylphenoxide) (ATPH).
Journal ArticleDOI
New approach for natural product synthesis using main group organometallic reagents
TL;DR: A review of the state-of-the-art of organoaluminum- or organoboron-mediated asymmetric reactions in natural product synthesis can be found in this article.

Scalable Synthesis of a Chiral Selenium π-Acid Catalyst and Its Use in Enantioselective Iminolactonization of β,γ-Unsaturated Amides
Yuta Otsuka,Yuto Shimazaki,Hitoshi Nagaoka,Keiji Maruoka,Keiji Maruoka,Takuya Hashimoto,Takuya Hashimoto +6 more
TL;DR: Improved synthesis of this chiral selenium π-acid catalyst is reported, which allows access to a large quantity of the catalyst as the diselenide and the catalyst is tested in the oxidative cyclization of N-methoxy β,γ-unsaturated amides to give iminolactones with high enantioselectivities.
