Abstract: The invention relates to a process to produce a (1r,4r)-4-substituted cyclohexane-1-amine [further referred as trans-4-substituted cyclohexane-1-amine] of formula (T), starting from a diastereomeric mixture of 4-substituted cyclohexane-1-amines (formula (C) + formula (T)) or any salt of them by using a single transaminase biocatalyst in whole-cell, soluble or immobilized form in the presence of an amine acceptor used in sub-equimolar up to equimolar quantities in batch mode or in continuous-flow mode. In the first aspect of the present invention 2-(trans-4-aminocyclohexyl)acetic acid esters, more preferably a C1-6 alkyl esters, particularly 2-(trans-4-aminocyclohexyl)acetic acid ethyl ester may be produced. In the second aspect of the present invention hydroxyl-protected or protective group-free trans-4-(2-hydroxyethyl)cyclohexan-1-amines, particularly trans-4-(2-hydroxyethyl)cyclohexan-1-amine may be produced. In the third aspect of the present invention protected 2-(trans-4-aminocyclohexyl)acetaldehydes, particularly trans-4-((1,3-dioxolan-2-yl)methyl)cyclohexan-1-amine may be produced.

Abstract: A high-LPI lysolecithin and methods related to the same are provided. The high-LPI product is produced through the reaction of lecithin with a unique method using solvent, buffer, and phospholipase. Using the current production method, LPI content is increased from 1.4% to 2.5-13.1% using regular soy lecithin as the starting material and LPC, LPE and LPA contents are also increased from 5.1%, 2.0%, 1.0% to 15.8%, 14.6% and 4.4% respectively.
