Abstract:

Arylated heterocyclic fluorophores are particularly useful scaffolds for numerous applications, such as bioimaging or synthetic photochemistry. While variation of the substitution pattern at the heterocycle and aryl groups allows dye modulation, the bond rotational barriers are also strongly affected. Unsymmetrically substituted ring systems of rotationally restricted arylated heterocycles therefore lead to configurationally stable atropisomeric fluorophores. Herein, we describe these characteristics by determining the properties and configurational stability of atropisomeric, tri-ortho-substi

Abstract:

Unnatural cyclic α-amino acids play an important role in the search for biologically active compounds and macromolecules. Enantiomers of natural amino acids with a D configuration are not naturally encoded, but can be chemically synthesized. The crystal structures of two enantiomers obtained by a method of stereoselective synthesis, namely (5R,8S)-8-tert-butyl-7-methoxy-8-methyl-9-oxa-6-azaspiro[4.5]decane-2,10-dione, (1), and (5S,8R)-8-tert-butyl-7-methoxy-8-methyl-9-oxa-6-azaspiro[4.5]decane-2,10-dione, (2), both C14H21NO4, were determined by X-ray diffraction. Both enantiomers crystallize i

Abstract:

An efficient methodology has been developed for the synthesis of a variety of novel trifluoroacetylated enaminones by using trifluoroacetic anhydride in DCE as solvent and DBU as a base via electrophilic trifluoroacetylation. X-ray crystallographic studies confirmed the trifluoroacetylation and E stereoisomeric form of the novel compounds. The synthetic strategy has the advantage of using an inexpensive and non-toxic base for producing excellent yields. Synthons bearing variety of functional groups may be further extended for the formation of heterocyclic compounds.

Abstract:

Intra-molecular Diels–Alder (IMDA) reactions of tethered trienes can furnish two distinct diastereoisomeric products, the cis (i.e., endo) stereoisomer and the trans (i.e., exo) stereoisomer. Experimental evidence shows a quite high cis stereo-selectivity for 10-link compounds (cis/trans = 70:30), while 11- and 12-links compounds exhibit no particular selectivity. DFT (B3LYP/6-31G*) computations provide useful insights into the origins of this amazing stereo-selectivity. The cyclization path towards trans stereo-isomer is always thermodynamically favored, whatever the size of the system. The h
