Paragraph 0121-0123; 0126, (2020/05/14)
The invention provides an amino acid derivative, a feed composition and application thereof, and belongs to the technical field of animal feed additives. The amino acid derivative is a compound with astructure shown as a formula (I), and a stereoisomer, a tautomer, a solvate, a metabolite, a feed acceptable salt or a prodrug thereof. In formula (I) shown in the specification, Z is a C1-C3 alkylene group. X is an indole ring group with a structure shown as a formula (II). The formula (II) is shown in the specification, wherein Y is phenyl with the structure shown in the formula (III) shown inthe specification. The amino acid derivative is used as an animal feed additive, and can promote the growth of animals and improve the feed conversion.
Iron(III)/O2-Mediated Regioselective Oxidative Cleavage of 1-Arylbutadienes to Cinnamaldehydes

A simple, efficient, and environmentally benevolent regioselective oxidative cleavage of 1-arylbutadienes to cinnamaldehydes mediated by iron(III) sulfate/O2 has been developed. The reaction offered good yields and excellent regioselectivity and showed good functional group tolerance (31 examples). The method is important, as few reports with limited substrate scope are available for such excellent oxidative cleavage of conjugated dienes.
Kinetic resolution of acyclic secondary allylic silyl ethers catalyzed by chiral ketones

Kinetic resolution of acyclic secondary allylic silyl ethers by chiral dioxiranes generated in situ from chiral ketones (R)-1 and (R)-2 and Oxone was investigated. An efficient and catalytic method has been developed for kinetic resolution of those substrates with a CCl3, tert-butyl, or CF3 group at the α-position. In particular, high selectivities (S up to 100) were observed for kinetic resolutions of racemic α-trichloromethyl allylic silyl ethers 7 and 9-15 catalyzed by ketones (R)-2. Both the recovered substrates and the resulting epoxides were obtained in high enantiomeric excess. On the basis of steric and electrostatic interactions between the chiral dioxiranes and the racemic substrates, a model was proposed to rationalize the enantioselectivities and diastereoselectivities in the chiral ketone-catalyzed kinetic resolution process.
