Acyl oximes are directly used as the acyl radical precursors in the hydroacylation reactions for the first time. In this work, acyl radicals can be effectively generated via β-scission of a phosphoranyl radical under photocatalytic conditions. As a result, the hydroacylation of alkenes triggered by the resulting acyl radicals leads to facile syntheses of a range of valuable ketones.

The first diastereoselective synthesis of β-amino ketone and β-amino acid derivatives by palladium-catalyzed conjugate addition of arylboronic acids to chiral β-enamino ketones and β-enamino esters is reported. The catalytic system employing (S)-4-(tert-butyl)oxazolidin-2-one as the chiral auxiliary in water under an air atmosphere provides β-amino ketone and β-amino acid derivatives in high yields with excellent diastereoselectivity.

Simple and efficient methods were developed for sp2-sp3 and sp3-sp3 C-C bond-activation reactions of 2-substituted 1,3-diketones. 3-Substituted 3-bromopentane-2,4-diones were deacylated in the presence of an aromatic compound and a silica gel supported Bronsted acid containing sulfonic groups. The carbocation formed by cleavage of the sp3-sp3 C-C bond of the dione alkylated the aromatic compound.

Alkylation of various β-ketoesters IIIa-d with bis(p-methoxycarbonylphenyl)bromomethane (II) and bis(p-chlorophenyl)bromomethane (VI) followed by cleavage of ethoxycarbonyl group or hydrolysis and esterification gave methoxycarbonylphenyl and chlorophenyl analogues of ar-juvabione, respectively.Condensation of bis(p-methoxycarbonylphenyl)methanol (IX) with isovaleryl and trichloroacetyl chloride gave isovalerate X and trichloroacetate XI, respectively, while the condensation of bis(p-chlorophenyl)methanol (XII) with isovaleryl chloride and citronellyl bromide yieldedisovalerate XIII and citronellyl ether XIV, respectively.The methoxycarbonylation of aryl-alkyl ketones XVa-d with oxalyl chloride and treatment with methanol furnished various ar-juvabione analogues XVIa-d.The compounds Vb, Vc, Vd, XVIb, and XVIc showed high activity against Dysdercus koenigii at 1μg concentration.
