Organic zinc refers to the complex formed by zinc and organic ligands (such as zinc glucate ) or chelates (such as zinc methionine). Amino acid zinc chelates have become the main development trend of trace element zinc additives today. Organic zinc plays a major role in rubber, plant feed, feed, and livestock production.
Organozinc reagent is one of the earliest organometallic reagents discovered. Due to the low reactivity of organozinc reagents, they have good functional group compatibility, high chemical, regio and stereoselectivity and other advantages. In addition, organic zinc reagents can undergo metal exchange reactions with many transition metal salts or complexes to obtain highly active organic transition metal reagents, which can react with a variety of electrophiles.
Through the carbon chain extension reaction of β-diketones with the participation of organozinc reagents, the ALdol condensation and C-C bond migration reactions of α-bromoketones, and the Semipinacol regeneration of α-bromoalcohols Through the study of exclusion reactions, we have expanded the application scope of organozinc reagents in organic synthesis. These new synthesis methods are expected to have special applications in some fields such as science and the total synthesis of natural products.
The organic zinc reagent is the same as the Grignard reagent. It adds to the carbonyl group of aldehydes and ketones to form a bromide zinc compound of β-carbonyl acid ester. After acidification and Separate to obtain β-carbonyl acid ester. It can also react with certain esters to form β-keto acid lipids.
The method of zinc supplementation can be to add inorganic zinc or organic zinc to the feed. Inorganic zinc mainly includes zinc sulfate, zinc oxide, zinc carbonate, etc. Organic zinc refers to the organic zinc formed by organic ligands. Complexes or chelates, such as zinc gluconate, zinc methionine, etc. Different forms of zinc have different utilization rates in the body. Generally speaking, the biological potency of inorganic zinc is lower than that of organic zinc, while organic zinc is lower than Amino acid chelation zinc.
