Abstract
AbstractA new one-pot synthesis of 3-(1,2,3,4-tetrahydroisoquinolin-1-yl)-isoquinolin-1(2H)-ones by DEAD-promoted oxidative Ugi–Wittig reaction was developed. The sequential reactions of (2-carboxybenzyl)triphenylphosphonium salts, isocyanides, and N-aryl-1,2,3,4-tetrahydroisoquinolines produced 3-(1,2,3,4-tetrahydroisoquinolin-1-yl)-isoquinolin-1(2H)-ones in moderate to good overall yields in the presence of DEAD and Et3N.

Abstract
A formal hydroxylation/cyclization of cyclopropanemethanols with DMSO is described, which involves isomerization and cyclization under Tf2O catalysis. This reaction undergoes ring-opening of the cyclopropane moiety to generate homoallylic alcohols, which react with DMSO to produce 3-benzylidenetetrahydrofurans. With various substituted groups on cyclopropanemethanols the reactions proceed smoothly and the desired 3-benzylidenetetrahydrofurans are obtained in moderate to good yields.

Abstract
The Ru(ii)-catalyzed tunable [5+1]/[5+2] annulation of N-benzo[d]imidazole indolines with propargyl carbonates has been realized for the divergent synthesis of ring-fused quinazolines and 1,3-benzodiazepines bearing various functional groups. These transformations represent an efficient and practical strategy in constructing complex heterocycles via diversified C-H functionalization. A distinctive acidity-controlled reaction manner has been clarified to account for the chemoselectivity.

Abstract
During the past decades, synthetic organic chemistry discovered that directing group assisted C-H activation is a key tool for the expedient and siteselective construction of C-C bonds. Among the various directing group strategies, bidentate directing groups are now recognized as one of the most efficient devices for the selective functionalization of certain positions due to fact that its metal center permits fine, tunable, and reversible coordination. The family of bidentate directing groups permit various types of assistance to be achieved, such as N,N-dentate, N,O-dentate, and N,S-dentate auxiliaries, which are categorized based on the coordination site. In this review, we broadly discuss various C-H bond functionalization reactions for the formation of C-C bonds with the aid of bidentate directing groups.

Abstract
An efficient and practical Rh(III)-catalyzed redox-neutral [4 + 1] annulation of N-phenoxy amides with α, α-difluoromethylene alkynes has been realized to give direct access to the Z-configured monofluoroalkenyl dihydrobenzo[ d]isoxazole framework with broad substrate compatibility and good functional group tolerance, which was further enhanced by the late-stage C-H modification of complex bioactive compounds. Subsequent density functional theory calculations revealed that the stereoselective β-F elimination involving an allene species played a decisive role in determining the reaction outcome and such Z-selectivity.

Abstract
The Rh(III)-catalyzed synthesis of 4-substituted isoquinolones and 2-pyridones by the annulation of N-methoxyamides and nitroalkenes has been developed. Both aliphatic and aromatic nitroalkenes were effective inputs. Annulations also proceeded for aromatic, alkenyl, and heteroaromatic C-H bond starting materials. Moreover, benzoic acid provided a novel nitrodihydroisocoumarin. The structure and relative stereochemistry of this compound, which is an oil at room temperature, was determined unambiguously by single crystal X-ray diffraction of its inclusion complex with a hydrogen-bonded host framework.

Abstract
Dioxane was found to be involved in the reaction of 2-(arylethynyl)benzaldehydes and 3-aminopyrazine-2-carbohydrazide, and underwent a ring-opening reaction catalyzed by AgOTf. This domino type procedure provided an efficient method for the synthesis of 3-aryl-1-(2-(vinyloxy)ethoxy)isoquinolines in good yields via the loss of a molecule of 3-aminopyrazine-2-carboxamide.
