A monoprotected amino acid Bz-Gly-OH assists in the allylic alkylation of a variety of ketones, β-keto esters, aldehydes, etc., during enamine-palladium catalysis to gave alkylated products such as R1C(O)CHR2CH2CH=CHAr [R1 = Me, Et, n-Pr; R2 = Et, C(O)OMe, C(O)OEt, C(O)OBn, etc.; R1R2 = (CH2)3, (CH2)4, (CH2)5, etc.]. D. functional theory calculations revealed that Bz-Gly-OH assisted in the formation of an enamine that attacks the π-allylpalladium complex via an outer sphere mechanism. The preliminary result pointed to an asym. allylic alkylation under a new mode of bifunctional catalysis. In the experiment, the researchers used many compounds, for example, (1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5Category: alcohols-buliding-blocks).
(1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5) belongs to alcohols. Alcohols are weak acids. The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Category: alcohols-buliding-blocks
