Synthesis and Biological Evaluation of Cruentaren A Analogues
Authors: Vintonyak Viktor V. , Calà Marcellino , Lay Frank , Kunze Brigitte , Sasse Florenz , Maier Martin E. 
Published: February 2008

AbstractThe complex macrolide cruentaren A is a highly selective and potent inhibitor of F‐ATPase (F‐type adenosine triphosphatase). As it shows some resemblance to benzolactone enamides like apicularen A, it was of interest to perform some structure–activity studies to delineate the key functional groups that are responsible for the activity. Building upon our previously developed route to cruentaren A, which is based on a ring‐closing alkyne metathesis reaction (RCAM), several cruentaren analogues were prepared. Replacement of the 3‐hydroxy hexanoic part with acids that lack the hydroxy group function resulted in a significant drop in cytotoxicity and F‐ATPase inhibition. Furthermore, two enamide analogues 23 and 50 were synthesized. However, these compounds were only cytotoxic in the micromolar range. Under the conditions for cleavage of the C3 aromatic methyl ether, the enamide function was transformed to the corresponding oxazinanone, resulting in analogues 25 and 52.
Asymmetric Friedel–Crafts Alkylation of Indoles with Methyl (E)‐2‐Oxo‐4‐aryl‐3‐butenoates Catalyzed by Sc(OTf)3/pybox

Published: February 2008

AbstractThe asymmetric Friedel–Crafts reaction between a series of substituted indoles 2 a–l and methyl (E)‐2‐oxo‐4‐aryl‐3‐butenoates 3 a–c has been efficiently catalyzed by the scandium(III) triflate complex of (4′S,5′S)‐2,6‐bis[4′‐(triisopropylsilyl)oxymethyl‐5′‐phenyl‐1′,3′‐oxazolin‐2′‐yl]pyridine (pybox; 1). Substituted 4‐(indol‐3‐yl)‐2‐oxo‐4‐arylbutyric acid methyl esters 4 a–n were usually formed in excellent yields and the enantioselectivity was up to 99 % ee, irrespective of the electronic character of the substituent and its location on the indole ring, albeit with the exclusion of position 2. The adducts could be obtained as stable enol tautomers and the equilibrium with the keto structure is discussed. The X‐ray crystal structure determination of 4 m indicated the 4R absolute configuration, thus confirming the proposal of Jørgensen for 4 i. The sense of the stereoinduction can be rationalized by the same octahedral complex 5 between 3, pybox 1, and scandium triflate already proposed for the Diels–Alder/hetero‐Diels–Alder and the Mukaiyama–aldol reactions of pyruvates.
Bis(BF2)‐2,2′‐Bidipyrrins (BisBODIPYs): Highly Fluorescent BODIPY Dimers with Large Stokes Shifts

Published: February 2008

AbstractFour new dimeric bis(BF2)‐2,2′‐bidipyrrins (bisBODIPYs), and their corresponding BODIPY monomers, have been prepared and studied with respect to their structural and photophysical properties. The solid‐state molecular structure of the dimers and the relative orientation of the subunits have been revealed by an X‐ray diffraction study, which showed that the molecules contain two directly linked BODIPY chromophores in a conformationally fixed, almost orthogonal arrangement. Two of the fluorine atoms are in close contact with each other and the 19F NMR spectra show a characteristic through‐space coupling in solution. The new chromophores all exhibit a clear exciton splitting in the absorption spectra with maxima at about 490 and 560 nm, and are highly luminescent with an intense emission band at around 640 nm. The Stokes shift, which is the difference between the maximum of the lowest‐energy absorption band and the maximum of the emission band, has a typical value of 5 to 15 nm for simple BODIPYs, whereas this value increases to 80 nm or more for the dimers, along with a slight decrease in fluorescence quantum yields and lifetimes. These properties indicate potential uses of these new fluorophoric materials as functional dyes in biomedical and materials applications and also in model compounds for BODIPY aggregates.
