Abstract
The synthesis, X-ray crystal structures, and calculated strain energies are reported for a homologous series of 11- to 14-membered drug-like cyclophane macrocycles, representing an unusual region of chemical space that can be difficult to access synthetically. The ratio of macrocycle to dimer, generated via a copper catalyzed azide-alkyne cycloaddition macrocyclization in flow at elevated temperature, could be rationalized in terms of the strain energy in the macrocyclic product. The progressive increase in strain resulting from reduction in macrocycle ring size, or the introduction of additional conformational constraints, results in marked deviations from typical geometries. These strained cyclophane macrocyclic systems provide access to spatial orientations of functionality that would not be readily available in unstrained or acyclic analogs. The most strained system prepared represents the first report of an 11-membered cyclophane containing a 1,4-disubstituted 1,2,3-triazole ring and establishes a limit to the ring strain that can be generated using this macrocycle synthesis methodology.

Abstract
A facile substrate-encapsulated RCM-based synthesis of 7-membered lactones is reported. Coordination of the alpha,omega-dienyl ester precursor to the bulky Lewis acid (LA) aluminum tris(2,6-diphenylphenoxide) (ATPH) provides a protective extended steric pocket to the olefin moieties, thereby favoring intramolecular RCM over intermolecular ADMET oligomerization. The LA-encapsulated esters undergo ring-closure in the presence of Ru-based olefin metathesis catalysts to give previously difficult-to-access 7-membered beta,gamma- and gamma,delta-unsaturated lactones in good yields.

Abstract
A convenient Grubbs II metathesis provides dihydrooxasilines by relay RCM (RRCM). Dihydrooxasilines undergo ring opening to give Z-vinyl silanes. These can then be converted to Z-vinyl iodides. This sequence provides a short, high yield, and convenient route to trisubstituted Z-vinyl iodides, useful intermediates for the preparation of polypropionate antibiotics.

Abstract
Two novel and efficient strategies for the synthesis of hitherto unknown N-shifted and ring-expanded buflavine analogues are presented. Construction of the medium-sized ring system of the title molecules, a difficult task due to the high activation energy needed for the ring-closure with the additional rigidity imposed by the biaryl skeleton, was achieved by using Suzuki-Miyaura biaryl coupling and a ring-closing metathesis reaction as the key steps. The combination of a second-generation Grubbs catalyst and microwave irradiation proved to be highly useful in generating the otherwise difficult to obtain medium-sized ring system of the buflavine analogues.

Abstract
Efficient direct en-yne metathesis of strained macrocyclic systems is possible using highly active Grubbs-Hoveyda second-generation catalyst and when exploiting fluoroarene-arene gearing interactions. These interactions are effective even under high reaction temperatures and in the presence of a competitive pi-rich solvent such as toluene. These results suggest that efficient pi-pi stacking or pi-lp interactions between auxiliaries containing pentafluorophenyl and 3,5-bis(trifluoromethyl)phenyl groups are responsible for the good yields of macrocyclization products. The 3,5-bis(trifluoromethyl)benzyl gearing elements provide higher yields and greater E-selectivity in the macrocyclic en-yne metathesis to form model paracyclophanes that could be applied toward the preparation of members of the longithorone family of natural products.
