Journal ArticleDOI
Design of chiral tin(IV) aryloxide as a mild Lewis acid catalyst for enantioselective Diels–Alder reaction
TL;DR: In this paper, a chiral Sn(IV) aryloxide Lewis acid has been designed and prepared from SnCl4 and (S)-3,3′-bis (3,5-bis(trifluoromethyl)phenyl)-1,1′-bi-2-naphthol.
Journal ArticleDOI
Modular synthesis of axially chiral 3,3'-disilyl dicarboxylic acids by silalactones.
TL;DR: In this paper, the method is based on the dehydrogenative silalactonization of axially chiral dicarboxylic acid (I) with chlorohydrosilanes, followed by ring opening with Grignard compounds.
Journal ArticleDOI

Masaki Morita,Shuntaro Kojima,Megumi Ohkubo,Hiroyuki Koshino,Daisuke Hashizume,Go Hirai,Keiji Maruoka,Mikiko Sodeoka +7 more
TL;DR: A method is newly established for the preparation of an optically active synthetic intermediate by enzymatic kinetic resolution and provides access to both natural and nonnatural right‐side physalin structures.
Journal ArticleDOI
Tris(2,6-diphenylbenzyl)amine (TDA) and tris(2,6-diphenylbenzyl)phosphine (TDP) with unique bowl-shaped structures: synthetic application of functionalized TDA to chemoselective silylation of benzylic alcohols
TL;DR: In this paper, a new strategy for obtaining the formal steric hindrance of tertiary amines by remote steric factors is described by designing the bowl-shaped, structurally unique tris(2,6-diphenylbenzyl)amine (TDA).
Journal ArticleDOI
Hypercoordination of aluminum: Evidence for the implication of pentacoordinate complexes in the R2AlCl-promoted reduction of alkoxycarbonyl substrates
TL;DR: R 2 AlCl-promoted reductions of alkoxy carbonyl substrates with Bu 3 SnH were found to proceed diastereoselectively through the formation of pentacoordinate chelate-type complexes which have been characterized by 13 C NMR spectroscopy.
