Decarboxylative Borylation of mCPBA-Activated Aliphatic Acids

A decarboxylative borylation of aliphatic acids for the synthesis of a variety of alkylboronates has been developed by mixing m-chloroperoxybenzoic acid (mCPBA)-activated fatty acids with bis(catecholato)diboron in N,N-dimethylformamide (DMF) at room temperature. A radical chain process is involved in the reaction which initiates from the B-B bond homolysis followed by the radical transfer from the boron atom to the carbon atom with subsequent decarboxylation and borylation.

Synthesis and biological evaluation of new berberine derivatives as cancer immunotherapy agents through targeting IDO1

To discover small-molecule cancer immunotherapy candidates through targeting Indoleamine 2,3-dioxygenase 1 (IDO1), twenty–five new berberine (BBR) derivatives defined with substituents on position 3 or 9 were synthesized and examined for repression of IFN-γ-induced IDO1 promoter activities. Structure–activity relationship (SAR) indicated that large volume groups at the 9-position might be beneficial for potency. Among them, compounds 2f, 2i, 2n, 2o and 8b exhibited increased activities, with inhibition rate of 71–90% compared with BBR. Their effects on IDO1 expression were further confirmed by protein level as well. Furthermore, compounds 2i and 2n exhibited anticancer activity by enhancing the specific lysis of NK cells to A549 through IDO1, but not cytotoxicity. Preliminary mechanism revealed that both of them inhibited IFN-γ-induced IDO1 expression through activating AMPK and subsequent inhibition of STAT1 phosphorylation. Therefore, compounds 2i and 2n have been selected as IDO1 modulators for small-molecule cancer immunotherapy for next investigation.

The invention aims to provide a compound, which has a high radiation susceptibility, good dissolvability in a radiation sensitivity composition and good transparency of solidified film when the compound is used as a photo polymerized initiator. A radiation sensitivity compound can obtain the solidified film with good transparency and surface hardness. The invention is a compound expressed in the following formula (1), where R4 is alicyclic alkyl with one part of or the whole hydrogen atoms being replaced by alkyl with 1-12 carbon atoms. The invention is the radiation sensitivity composition having the compound (A) as the photo polymerized initiator and the polymerized compound (B) having ethylene unsaturated double bonds. The radiation sensitivity composition preferably includes alkali soluble resin (C).

Palladium-Catalyzed Alkoxycarbonylation of Unactivated Secondary Alkyl Bromides at Low Pressure

Catalytic carbonylations of organohalides are important C-C bond formations in chemical synthesis. Carbonylations of unactivated alkyl halides remain a challenge and currently require the use of alkyl iodides under harsh conditions and high pressures of CO. Herein we report a palladium-catalyzed alkoxycarbonylation of secondary alkyl bromides that proceeds at low pressure (2 atm CO) under mild conditions. Preliminary mechanistic studies are consistent with a hybrid organometallic-radical process. These reactions efficiently deliver esters from unactivated alkyl bromides across a diverse range of substrates and represent the first catalytic carbonylations of alkyl bromides with carbon monoxide.

Palladium-catalyzed double activation and arylation of 2° and 3° C(sp3)-H bonds of the norbornane system: Formation of a C-C bond at the bridgehead carbon and bridgehead quaternary stereocenter

Pd-catalyzed activation and direct arylation of both 2° and the bridgehead 3° (sp3) C-H bonds and an unprecedented C-C bond formation at the bridgehead carbon of the norbornane system are reported. The assembly of bridgehead-substituted norbornane frameworks having contiguous stereocenters was accomplished. X-ray crystal structure analysis of representative molecules unambiguously established the stereochemistry.

Hypervalent iodine catalyzed hofmann rearrangement of carboxamides using oxone as terminal oxidant

Hofmann rearrangement of carboxamides to carbamates using Oxone as an oxidant can be efficiently catalyzed by iodobenzene. This reaction involves hypervalent iodine species generated in situ from catalytic amount of PhI and Oxone in the presence of 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) in aqueous methanol solutions. Under these conditions, Hofmann rearrangement of various carboxamides affords corresponding carbamates in high yields.

193-nm photoresists based on norbornene copolymers with derivatives of bile acid

We synthesized new chemically amplified photoresists for 193-nm lithography. Norbornene substituted with a derivative of bile acid was copolymerized with maleic anhydride by free radical polymerization. The resulting copolymers have good transmittance at 193 nm and possess excellent thermal stability up to 260 °C. With the standard developer, the resists formulated with the copolymers form 0.15-0.18 μm patterns at doses of 6-7 mJ cm-2 using an ArF excimer laser stepper.
