چکیده

[structure: see text] The first enantioselective synthesis of the polyketide antibiotics basiliskamides A and B, which exhibit potent in vivo activity against Candida albicans and Aspergillus fumigatus, has been achieved. Serial asymmetric crotylsilane and crotylboronate additions established the C7-C10 stereochemical tetrad. Takai iodoolefination and palladium-mediated cross-coupling were used to install the (Z,E)-vinyl acrylamide. Spectroscopic data is consistent with the assignment of the absolute configurations of the natural products as (7S,8S,9R,10S).

Tupuseleiamides and basiliskamides, new acyldipeptides and antifungal polyketides produced in culture by a Bacillus laterosporus isolate obtained from a tropical marine habitat.

Laboratory cultures of PNG 276, a Bacillus laterosporus isolate obtained from coastal waters off Papua New Guinea, have been shown to produce the novel metabolites basiliskamide A (1), basiliskamide B (2), tupuseleiamide A (3), and tupusleiamide B (4). The structures of 1 to 4 were elucidated by analysis of spectroscopic data and chemical degradation. Basiliskamides A (1) and B (2) show potent ...

Synthesis of Boron-Aluminum Nitride Thin Film by Chemical Vapour Deposition Using Gas Bubbler

Boron included aluminium nitride (B-AlN) thin films were synthesized on silicon (Si) substrates through chemical vapour deposition ( CVD ) at 773 K (500 °C). tert-buthylamine (tBuNH2) solution was used as nitrogen source and delivered through gas bubbler. B-AlN thin films were prepared on Si-100 substrates by varying gas mixture ratio of three precursors. The structural properties of the films ...

Optimization of biocatalytic synthesis of Chitosan Ester using response surface methodology

Esterification of chitosan with adipic acid catalyzed by immobilized Candida antarctica lipase B was carried out in this study. Response surface methodology (RSM) based on a four-factor- five-level small central composite design (SCCD) was employed to model and analyze the reaction. A total of 21 experiments representing different combinations of the four reaction parameters including ch...
