Palladium(0)/NHC‐Catalyzed Reductive Heck Reaction of Enones: A Detailed Mechanistic Study
Authors: Raoufmoghaddam Saeed , Mannathan Subramaniyan , Minnaard Adriaan J. , de Vries Johannes G. , Reek Joost N. H. 
Published: November 2015

AbstractWe have studied the mechanism of the palladium‐catalyzed reductive Heck reaction ofpara‐substituted enones with 4‐iodoanisole by usingN,N‐diisopropylethylamine (DIPEA) as the reductant. Kinetic studies and in situ spectroscopic analysis have provided a detailed insight into the reaction. Progress kinetic analysis demonstrated that neither catalyst decomposition nor product inhibition occurred during the catalysis. The reaction is first order in the palladium and aryl iodide, and zero order in the activated alkene, N‐heterocyclic carbene (NHC) ligand, and DIPEA. The experiments with deuterated solvent ([D7]DMF) and deuterated base ([D15]Et3N) supported the role of the amine as a reductant in the reaction. The palladium complex [Pd0(NHC)(1)] has been identified as the resting state. The kinetic experiments by stopped‐flow UV/Vis also revealed that the presence of the second substrate, benzylideneacetone1, slows down the oxidative addition of 4‐iodoanisole through its competing coordination to the palladium center. The kinetic and mechanistic studies indicated that the oxidative addition of the aryl iodide is the rate‐determining step. Various scenarios for the oxidative addition step have been analyzed by using DFT calculations (bp86/def2‐TZVP) that supported the inhibiting effect of substrate1by formation of resting state [Pd0(NHC)(1)] species at the cost of further increase in the energy barrier of the oxidative addition step.
Cyano‐Schmittel Cyclization through Base‐Induced Propargyl‐Allenyl Isomerization: Highly Modular Synthesis of Pyridine‐Fused Aromatic Derivatives
Authors: You Xu , Xie Xin , Chen Haoyi , Li Yuxue , Liu Yuanhong 
Published: November 2015

AbstractThe cyano‐Schmittel cyclization of in situ‐generated cyano‐allenes has been carried out. The DFT calculation results suggest that the diradical pathway plays a major role in this cyclization. The reactions can be conveniently performed in a one‐pot manner through cascade Sonogashira coupling of terminal cyano‐ynes with organic halides, followed by base‐promoted propargyl‐allenyl isomerization/cyclization, leading to an efficient access to pyridine‐fused polycyclic architectures. In particular, a large variety of aryl or heteroaryl rings such as furans, thiophenes and pyridines can be incorporated into the follow‐up cyano‐Diels–Alder reactions, highlighting the great synthetic utility of this chemistry.
Remote Construction of Chiral Vicinal Tertiary and Quaternary Centers by Catalytic Asymmetric 1,6‐Conjugate Addition of Prochiral Carbon Nucleophiles to Cyclic Dienones

Published: November 2015

AbstractAn unprecedented remote construction of chiral vicinal tertiary and quaternary centers by a catalytic asymmetric 1,6‐conjugate addition of prochiral carbon nucleophiles to cyclic dienones has been developed. Both 5H‐oxazol‐4‐ones and 2‐oxindoles were found to be very efficient carbon nucleophiles in this reaction at a remote position, giving products with excellent enantio‐ and diastereoselectivities (up to 99 % ee and >19:1 d.r. for 5H‐oxazol‐4‐ones and up to 97 % ee and >19:1 d.r. for 2‐oxindoles).
Evaluation of the Synthetic Potential of an AHBA Knockout Mutant of the Rifamycin Producer Amycolatopsis mediterranei
Authors: Bułyszko Ilona , Dräger Gerald , Klenge Anja , Kirschning Andreas 
Published: November 2015

AbstractSupplementing an AHBA(−) mutant strain of Amycolatopsis mediterranei, the rifamycin producer, with a series of benzoic acid derivatives yielded new tetraketides containing different phenyl groups. These mutasynthetic studies revealed unique reductive properties of A. mediterranei towards nitro‐ and azidoarenes, leading to the corresponding anilines. In selected cases, the yields of mutaproducts (fermentation products isolated after feeding bacteria with chemically prepared analogs of natural building blocks) obtained are in a range (up to 118 mg L−1) that renders them useful as chiral building blocks for further synthetic endeavors. The configuration of the stereogenic centers at C6 and C7 was determined to be 6R,7S for one representative tetraketide. Importantly, processing beyond the tetraketide stage is not always blocked when the formation of the bicyclic naphthalene precursor cannot occur. This was proven by formation of a bromo undecaketide, an observation that has implications regarding the evolutionary development of rifamycin biosynthesis.
Hypervalent Activation as a Key Step for Dehydrogenative ortho CC Coupling of Iodoarenes
Authors: Wu Yichen , Arenas Ismael , Broomfield Lewis Marc , Martin Eddy , Shafir Alexandr 
Published: November 2015

AbstractBuilding on earlier results, a direct metal‐free α‐ arylation of substituted cyclic 1,3‐diones using ArI(O2CCF3)2 reagents has been developed; unlike other arylative approaches, the arylated products retain the iodine substituent ortho to the newly formed CC bond. The mechanism is explored by using DFT calculations, which show a vanishingly small activation barrier for the CC bond‐forming step. In fact, taking advantage of an efficient in situ hypervalent activation, the iodoarenes are shown to undergo a cross‐ dehydrogenative CC coupling at the CH ortho to the iodine. When Oxone is used as terminal oxidant, the process is found to benefit from a rapid initial formation of the hypervalent ArI(OR)2 species and the sulfate‐accelerated final coupling with a ketone. This method complements the ipso selectivity obtained in the metal‐catalyzed α‐arylation of carbonyl compounds.
