Ni/Chiral Sodium Carboxylate Dual Catalyzed Asymmetric O-Propargylation

A highly enantioselective O-propargylation catalyzed by combining a phosphine-nickel complex and an axially chiral sodium dicarboxylate has been developed. The transformation features mild reaction conditions, a broad substrate scope, and excellent functional group tolerance, offering an efficient approach to an array of enantioenriched O-propargyl hydroxylamines. Mechanistic studies support the presumed role of the chiral carboxylate as a counterion for nickel catalysis enabling the discovery of highly stereoselective transformations. The power of this reaction is illustrated by its application in the asymmetric total synthesis of potent firefly luciferase inhibitors and (S)-dihydroyashabushiketol.

Chlorine, an atom economical auxiliary for asymmetric aldol reactions

An auxiliary strategy has been developed for asymmetric reactions of aldehydes in which the auxiliary itself is not chiral, but a single chlorine atom introduced via organocatalytic α-chlorination. The stereodirecting influence of the chlorine atom is then exploited prior to its removal by radical reduction. This strategy is demonstrated in the synthesis of several aldols (92-99% ee) and the natural products (+)-dihydroyashabushiketol and (+)-solistatin.

Total synthesis of (5S)-dihydroyashabushiketol

Enantiomerically pure (+)-(5S)-dihydroyashabushiketol 1a was obtained by the 1,3-dipolar cycloaddition of a nitrile oxide, generated from oxime 3b, to N-acryloyl bornane[10,2]sultam (2R)-2 (67%, 85% de, then crystallization 81%, 99% de), followed by reduc

Synthesis and evaluation of estrogen agonism of diaryl 4,5- dihydroisoxazoles, 3-hydroxyketones, 3-methoxyketones, and 1,3-diketones: A compound set forming a 4D molecular library

Stereoselective crossed aldol reaction via boron enolates generated from α-iodo ketones and 9-borabicyclo[3.3.1]nonane

Boron enolates were in situ-generated reductively by treating various α-iodo ketones such as 2-iodo-1-phenylpropan-1-one, 2-iodo-1-(4-methoxyphenyl)propan-1-one, 2-iodopentan-3-one, 2-iodo-2-methyl-1-phenylpropan-1-one, 3,4-dihydro-2-iodo-1(2H)-naphthalenone, 2-iodo-1-phenylethan-1-one and 1-iodo-4-phenylbutan-2-one with 9-borabicyclo[3.3.1]nonane (9-BBN). Aldols were produced in good yields with good to high diastereoselectivities by subsequent reaction of boron enolates thus formed with various aldehydes. Several boron enolates derived from α-iodo ketones and pinacolatoborane were successfully isolated by distillation, though the yields were rather moderate.

Synthesis and digestibility inhibition of diarylheptanoids: Structure- activity relationship

(±)-5-Hydroxy-1,7-bis-(4'-hydroxyphenyl)-3-heptanone (2a), (±)5- hydroxyl-1-(4'-hydroxyphenyl)-7-phenyl-3-heptanone (2b), (±)-5-hydroxy-7- (4'-hydroxyphenyl)-1-phenyl-3-heptanone (2c), and (±)-5-hydroxy-1,7- bis(phenyl)-3-heptanone (2d) have been synthesized to study the structure- activity relationship regarding digestibility inhibition in vitro in cow rumen fluid. The activities were compared with the activity of chiral (S)-2a and its glucoside platyphylloside (1), isolated from Betula pendula. Compound 2a was slightly less active, 2b and 2c were more active, and 2d was less active than (S)-2a and platyphylloside.
