Abstract

With the rapid development of intensive poultry breeding in China, the demand for poultry feed raw materials is increasing rapidly. However, the shortage of cereal feed and the persistently high price make it urgent for poultry feed production industry to explore cheaper energy alternative feed. Cassava has the characteristics of high yield, rich starch and fiber, high energy value, etc. It can replace corn or other energy feed in poultry breeding. The effective use of cassava products has been proved to reduce the feed cost of poultry production. However, the utilization of cassava is limited by many factors, such as low protein and anti-nutritional factors. Using correct processing and scientific formula, the addition level of cassava in poultry diet can be improved. In this paper, the nutritional characteristics, feed utilization, and application of cassava in poultry diet were reviewed, which provided a reference for the application of cassava in poultry diet.

Abstract

A novel approach to 2,5-disubstituted 1,3,4-oxadiazoles derivatives via a decarboxylative cyclization reaction by photoredox catalysis between commercially available α-oxocarboxylic acids and hypervalent iodine(III) reagent is described. This powerful transformation involves the coupling reaction between two different kinds of radical species and the formation of C-N and C-O bonds.

Abstract

An efficient synthesis of a variety of 2,5-disubstituted 1,3,4-oxadiazole derivatives via a cyclization reaction by photoredox catalysis between aldehydes and hypervalent iodine(III) reagents is described. The reaction proceeds under mild conditions and affords various target compounds in excellent yields. The commercially available aldehydes without preactivation and a simple visible-light-promoted procedure without any catalysts make this strategy an alternative to the conventional methods.

Abstract

A method for the synthesis of aryl trifluoroethyl ethers from fluoroalcohols and diaryliodonium salts in the presence of NaH and warm 1,2-dichloroethane has been developed. This transition metal free reaction is mild and facile. Various functional group including electron-withdrawing and electron-donating substrates in the diaryliodonium salts were tolerated in this transformation to afford the products in moderate to high yields.

Abstract

An efficient synthesis of a variety of quinazolinone derivatives via a direct cyclization reaction between commercially available anthranils and cyclic amines is described. The developed transformation proceeds with the merits of high step- and atom-efficiency, a broad substrate scope, and good to excellent yields, without additional catalysts, and offers a practical way for the preparation of rutaecarpine and its derivatives with structural diversity.
