We present herein a method for the controllable synthesis of 3-aryl-benzomorpholine and 2-aryl-benzomorpholine cycloadducts via cross-coupling/annulation between electron-rich 2-aminophenols and 4-vinylphenols.
A method for producing a resin for ink which includes reacting a lignin, a phenol, and an aldehyde so as to obtain a lignin-containing resol phenolic resin; and reacting the obtained lignin-containing resol phenolic resin with a rosin-based resin, and polyhydric alcohol.
A resin for ink is obtained by reaction of a lignin, phenols, aldehydes, a rosin-based resin, and polyhydric alcohol.

New alkenylphenols can be obtained directly, without protecting the phenol group from the condensation reaction between phenolic aldehydes and various phosphonium salts in the presence of potassium carbonate in protic and aprotic media, using a solid-liquid phase transfer.
