An efficient palladium-catalyzed cascade reaction of azides with isonitrile and amines is presented; it offers an alternative facile approach toward N -sulfonyl-, N -phosphoryl-, and N -acyl-functionalized guanidines in excellent yield. These series of substituted guanidines exhibit potential biological and pharmacological activities. In addition, the less reactive intermediate benzoyl carbodiimide could be isolated by silica gel column flash chromatography in moderate yield.

Zinc methyl 20-substituted 31-demethyl-bacteriopheophorbides-d were prepared through palladium-catalyzed cross-coupling of chlorophyll-a derivatives. The synthetic zinc 31-hydroxy-131-oxo-chlorins possessing a(n) (un)substituted ethynyl or butadiynyl group at the 20-position were good models for bacteriochlorophylls-c/d found solely in chlorosomes, the main light-harvesting antennas of green photosynthetic bacteria. Similarly as in natural chlorosomes, the synthetic models self-aggregated in an aqueous Triton X-100 solution to form large oligomers with red-shifted and broadened electronic absorption bands. While a phenyl group directly connected with the chlorin pi-system at the 20-position disturbed the chlorosomal self-aggregation, the insertion of an ethynylene group between the two functional groups reduced the steric hindrance around the 20-position and was useful for the facile formation of the self-aggregates. A similar substitution effect was observed in the 20-ethynyl to butadiynyl moieties bearing a sterically bulky trimethylsilyl group at the terminal position.

Ethynyl-bridged porphyrin-corrole dyads and triads were synthesized by using Pd(0) mediated coupling reactions and their structures were characterized by NMR, FT-IR, UV/Vis and fluorescence techniques. Besides spectroscopic techniques, computational studies at B3LYP/6-311G(d,p) level of DFT were also used to elucidate the minimum energy geometries and the molecular orbital characteristics of the new dyads and triads. DFT calculations pointed out the presence of charge separated donor-acceptor property between macrocycles of dyads and triads, and the emission studies indicated an excited state interaction between macrocycles, and energy transfer from the porphyrin to the corrole unit.

We report herein the first examples of a palladium-catalyzed enantioselective Cacchi reaction for the synthesis of indoles bearing a chiral C2-aryl axis. In the presence of a catalytic amount of Pd(OAc)2 and (R,R)-QuinoxP* ligand, reaction of N-aryl(alkyl)sulfonyl-2-alkynylanilides with arylboronic acids under oxygen atmosphere afforded enantioenriched 2,3-disubstituted indoles in high yields and enantioselectivity. The indole ring is constructed de novo in this process and a complexation-induced chirality transfer is proposed to account for the observed enantioselectivity.

Far-red (FR)/near-infrared (NIR) photosensitizer is highly desirable in image-guided photodynamic cancer therapy. Herein, a new conjugated polymer of poly(1,2-bis(4-((6-bromohexyl)oxy)phenyl)-1,2-diphenylethene-co-alt-9,10-anthraquinone) (PTPEAQ) consisting of tetraphenylethylene (TPE), an iconic aggregation-induced emission (AIE) active group as the electron donor, and anthraquinone (AQ) as the acceptor, is prepared for the first time through one-pot Suzuki polymerization. Encapsulation of PTPEAQ with a block copolymer followed by surface functionalization with anti-Her2 affibody yields PTPEAQ-NP-HER2. It shows bright AIE-active FR/NIR emission and efficient singlet oxygen generation under visible light irradiation, which has been successfully used for photodynamic cancer cell ablation using SKBR-3 cells, a type of breast cancer cell with HER2 overexpression on cell membrane, as an example.

C3-alkenylated and C3-(hetero)arylated 1H-indazoles are privileged structural motifs in numerous pharmaceuticals. Direct C3-alkenylation and C3-(hetero)arylation of 1H-indazoles have been significantly challenging because of the inert nature of this carbon center. Herein, we present an efficient mechanochemical strategy for palladium-catalyzed C-H/C-H cross-coupling to construct C3-alkenylated and C3-heteroarylated 1H-indazoles using low-cost copper oxidants with satisfactory product yields and broad functional group tolerance. The robustness of the developed protocols was further demonstrated by the unprecedented total mechanosynthesis of the intermediate of PLK4 inhibitor CFI-400945 and HIF-1alpha inhibitor YC-1.
