Abstract
A novel series of enediynes possessing pentafluorophenylsulfoxide have been developed. The innovative compounds possess antiproliferative activity against a broad panel of human cancer cells originating from breast, blood, lung, kidney, colon, prostate, pancreas or skin with IC50 ranging from 0.6 to 3.4 μM. The antiproliferative activity of enediynes in darkness is associated to their ability to compromise microtubule network. In addition, exposure to UV leads to double-stranded DNA cleavage caused by the newly synthesized molecules reducing further their IC50 in nanomolar range against human tumor cells, including chemo-resistant pancreatic cancer cells. Taken together, the examined data demonstrate that enediynes possessing pentafluorosulfoxide are promising molecules in the cancer therapy.

Abstract
We studied the variation in mechanism among different bispropargyl substrates-sulfone, sulfide, ether, amine, and methane-toward Garratt-Braverman (GB) cyclization using density functional theory calculations. Isomerization and cycloaddition are the key steps in the GB cyclization. To compare the reactivity among the various substrates, we computed the free energy of activation (ΔG(⧧)) for the cycloaddition and the cyclization steps, whereas we used the theoretically computed pKa values for the isomerization steps. Our results suggest that the sulfones undergo a relatively fast isomerization followed by slower cyclization, while the ethers undergo a slow isomerization followed by easy cyclization. The methanes and amines are similar to the ethers, and the sulfides showed intermediate behavior. We extended our study to unsymmetrical substrates and compare the results with experiments that suggest the isomerization to be the rate-limiting step for bispropargyl ethers, while cyclization through a diradical intermediate is crucial to the rate for the bispropargyl sulfones. On the basis of these findings, we made predictions on the selectivity of unsymmetrical bispropargyl sulfones, amines, methanes, and sulfides. This is the first detailed mechanistic study on the GB cyclization of bispropargyl substrates other than sulfones.

Abstract
The role of π-π interactions in controlling the reactivity and selectivity of a chemical reaction is only recently being explored, even though their ubiquitous role in the structural aspects is well known. We have studied Bergman cyclisation focusing on the effect of π-π interactions on the activation barrier and the variation of π-π interactions along the reaction coordinate. We used enediyne substrates that contain phenyl groups connected to the reaction centres (C1 and C6 atoms), separated by 0, 1 and 2 linker groups. The main difference between the substrates is that the Ph groups enjoy different flexibility to accommodate the changes occurring during the progress of the reaction. The path length of the minimum energy path is increased - shortest in the least flexible substrate (a) and longer in the more flexible ones (c, d and e). We calculated the interaction between the Ph groups, the π-π interaction, using BP86-D3BJ, B3LYP-D3BJ, M06-2X, B2PLYP-D3BJ, SCS-MP2, and SAPT. The BP86-D3BJ was found to be sufficiently accurate with a mean absolute deviation of 0.26 kcal mol(-1) with respect to the SAPT2+3 values. The variation in the π-π interaction shows different behaviour in a-e, and this can be correlated with the flexibility of the Ph groups to orient themselves to maintain the optimal relative orientation while conforming to the changes in the reaction coordinate. We analysed the relative orientation of the phenyl groups using certain geometric parameters that showed that when Ph groups can attain a relative orientation close to that of the free dimer, the interaction is maximum. Energy decomposition analysis using SAPT showed that the dispersive interaction is the major contributor (50-60%) to the attractive forces. The π-π interactions influenced the overall activation energy, either by destabilising the substrates or by stabilising the TS - resulting in a variation of about 3.5 kcal mol(-1) in activation energies in a-e. The effect of substituents of different electronic nature was assessed which showed that electron donating and electron withdrawing substituents increase the π-π interactions; however, the TS is more stabilised and hence activation energies are increased.

Abstract
Aryl-naphthalene diacetates prepared from bispropargyl sulfones, ethers and amines via Garratt-Braverman Cyclization have been selectively hydrolysed by AK lipase to the monoacetates 12a-c in high yields. The regioisomeric mono acetates 13a-c have been prepared by acetylation of the corresponding diols using the same enzyme. In both cases, the more exposed acetoxymethyl or hydroxy methyl attached to the naphthalene ring binds to the active site of the enzyme and underwent hydrolysis/acetylation. The method provides easy access to differentially protected aryl-naphthalenes which should allow further modifications.
