Bicontinuous lipidic cubic phases (LCPs) exhibit a combination of material properties that make them highly interesting for various biomaterial applications: they are nontoxic, biodegradable, optically transparent, thermodynamically stable in excess

Methyl heptalenecarboxylates of type A and B with π(1) and π(2) substituents in 1,4-relation (Scheme 1) were synthetized starting with dimethyl 1-methylheptalene-4,5-dicarboxylates 5b and 6b derived from 7-isopropyl-1,4-dimethylazulene (=guaiazulen

Azulenes and acetylenedicarboxylates react under acid catalysis (Bronsted or Lewis) and form (2aRS,8aSR)-2a,8a-dihydrocyclopenta[cd]azulene-1,2-dicarboxylates as intermediate products, which then dimerize by central bond-formation between C(2a1) and

It is shown in this ‘Part 2’ that heptaleno[1,2-c]furans 1 react thermally in a Diels–Alder-type [4+2] cycloaddition at the furan ring with vinylene carbonate (VC), phenylsulfonylallene (PSA), α-(acetyloxy)acrylonitrile (AAN), and (1Z)-1,2-bis

Incubation of deuteriated precursors in cultures of Flavobacterium produced specifically deuteriated carotenoids. Analysis of these led to several conclusions: i) Lycopene is a direct precursor of β,β-carotene. ii) Its terminal Me groups retain the

The reaction of guaiazulene (4) and dimethyl acetylenedicarboxylate (ADM) in tetralin or toluene, catalyzed by 5 mol-% of trifluoroacetic acid (TFA) at ambient temperature, leads to the formation of the corresponding heptalene-4,5-dicarboxylate 6 and

A new concept for molecular switches, based on thermal or photochemical double-bond shifts (DBS) in [4n]annulenes such as heptalenes or cyclooctatetraenes, is introduced (cf. Scheme 2). Several heptalene-1,2- and -4,5-dicarboxylates (cf. Scheme 4) wi

A series of novel lipids with designed functionalities were synthesized. These lipids are based on conjugation of α-amino acids and their esters, cationic, anionic, neutral, and photochromic moieties to the lipophilic 9-cis octadecenyl chains by ami
