The catalytic asym. synthesis of 3-allyl-3’aryl 2-oxindoles I [Ar = 4-methoxyphenyl, 2H-1,3-benzodioxol-5-yl, 2-(benzyloxy)-5-methylbenzen-1-yl, etc.; R = Me, Bn, allyl, X = H, 5-Br, 5-Cl, 5-OMe, 7-Me] has been shown via the Pd(0)-catalyzed decarboxylative allylation of allylenol carbonates. This methodol. provides access to a variety of 2-oxindole substrates I with all-carbon quaternary stereocenters (up to 94% ee) at the pseudobenzylic position under additive-free and mild conditions. The synthetic potential of this method was shown by the asym. synthesis of the tetracyclic core of the diketopiparazine-based alkaloid azonazine II. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Application In Synthesis of 4-Benzyloxyphenol).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Application In Synthesis of 4-Benzyloxyphenol
