The use of chemoselective ligation methods and orthogonal protection techniques allows access to Template-Assembled Synthetic Protein (TASP) mols. exhibiting a large variety of packing topologies. This is demonstrated for the synthesis of an antiparallel 4 ...
Oxiranecarbonitrile in basic aq. soln. at room temp. reacts regioselectively with inorg. phosphate to give the cyanohydrin of 2-oxoethyl phosphate ('glycolaldehyde phosphate'), a source of (the hydrate of) the free aldehyde, preferably in the presence of f ...
When heated in the presence of phosphoryl chloride, 2-anilinovinyl perfluoroalkyl ketones [e.g., 4-anilino-1,1,1-trifluoro-3-buten-2-one] gave 2-(perfluoroalkyl)quinolines [e.g., 2-(trifluoromethyl)quinoline]. As revealed by cross-over expts., an efficient ...
Sixteen polycyclic aromatic hydrocarbons (PAHs) were screened for their ability to be directly cytotoxic to a cell line from the rainbow trout gill, RTgill-W1. Exposure times of 2 h or less were sufficient for direct cytotoxicity to be detected, which appe ...
A general strategy for the synthesis of acerogenin-type diarylheptanoids contg. an endocyclic biaryl ether bond has been developed, and convergent total syntheses of acerogenin A, B, C, and L and aceroside IV have been accomplished. Cycloetherification of ...
Earth-abundant hydrogen evolution catalysts are essential for high-efficiency solar-driven water splitting. Although a significant amount of studies have been dedicated to the development of new catalytic materials, the microscopic assembly of these materi ...
In the context of the chem. of potentially prebiol. natural products it would be important to know whether, from a chem. point of view, glycolaldehyde phosphate could be considered as a potentially prebiol. natural material. In this connection, the reactio ...
The Scolytus multistriatus aggregation pheromone (S,S)-4-methyl-3-heptanol was prepd. via 2 stereoselective steps. Reaction of (Z)-2-butenyl potassium with FB(OMe)2 at -75 Deg gave (Z)-MeCH:CHCH2B(OMe)2 which reacted with EtCHO to give >60% 96:4 erythro-4- ...
Na2MoO4 has been found to have a peculiar catalytic behavior. The CH2O formation starts after a period of time at 670 Deg. Then the yield increases and reaches a max. after 12 h. The catalyst undergoes an extensive phase transformation prior to becoming ac ...
