Collective Asymmetric Total Synthesis of Cylindricines

Organic Letters, 2023
Collective asymmetric total synthesis of marine tricyclic alkaloids, cylindricines A–H, and the proposed structures of cylindricine I and J, was achieved in a concise manner from a single common spirocyclic pyrrolidine intermediate. A tandem chemoselective oxidation/intramolecular aza-Michael addition/epimerization was exploited to complete the ...

Sources of acid insoluble ash as marker of corn digestibility in broilers

Semina: Ciências Agrárias, 2022
The objective was to evaluate three sources of acid insoluble ash (AIA) (celite, kaolin, and sand), as indicators, to determine the apparent metabolizable energy of corn on a natural matter (AME) basis, dry matter digestibility coefficient (DMDC), and ...

Spot urine collection: A valid alternative to total urine collection for metabolomic studies in dairy cattle

Journal of Dairy Science, 2022
: Urine is a highly suitable biological matrix for metabolomics studies. Total collection for 24-h periods is the gold standard as it ensures the presence of all metabolites excreted throughout the day. However, in animal studies, it presents limitations

Influência do tempo de coleta e metodologias sobre a digestibilidade e o valor energético de rações para aves Effect of collection time and methodologies on the digestibility and energy value of poultry diets

Revista Brasileira de Zootecnia, 2005
Em um ensaio de digestibilidade, avaliou-se o método de coleta total de excretas e o método do óxido crômico como indicador. Determinou-se a energia metabolizável aparente corrigida pelo nitrogênio retido (EMAn) e os coeficientes de digestibilidade ...

Collective Total Synthesis of PPAPs: Total Synthesis of Clusianone via Intramolecular Cyclopropanation [PDF]

Natural Product Communications, 2013
The total synthesis of clusianone was accomplished through the stereoselective construction of a bicyclo[3.3.1]nonane derivative via a three-step sequence which has been utilized for the total syntheses of nemorosone garsubellin A and hyperforin: intramolecular cyclopropanation formation of a geminal dimethyl group and regioselective ring opening of ...

Collective Total Synthesis of 4‐Azafluorenone Alkaloids

European Journal of Organic Chemistry, 2023
Abstract4‐Azafluorenones are typically obtained by acid‐mediated cyclization of 2‐arylnicotinates. However, this approach fails to give 5‐oxygenated 4‐azafluorenones due to lactonization of 2‐(2‐alkoxy)phenylnicotinate intermediates. Herein, we report two modifications of established approaches to 4‐azafluorenone synthesis that, either in combination ...
