Resolution of N-protected cis- and trans-3-aminocyclohexanols via lipase-catalyzed enantioselective acylation in organic media

The enzymatic acylation of N-protected cis-and trans-1,3-aminocyclohexanols using lipases in organic solvents is described. By modifying certain reaction parameters such as the solvent, the lipase and the N-protecting group, it is possible to achieve high enantioselectivities and to obtain enantiomerically pure 3-aminocyclohexanols. The influence of the N-protecting group and the conformation of the substrate on the reaction rate was also studied.
Convenient Procedure for the Reduction of β-Enamino Ketones: Synthesis of γ-Amino Alcohols and Tetrahydro-1,3-oxazines

γ-Amino alcohols 3 can be easily synthesized in very good yields by reduction of enaminones 1 with Na in PrOH-tetrahydrofuran.The reaction is fast, easy to perform, inexpensive and the easily accesible starting materials provide a convenient entry to γ-amino alcohols.The relative configuration assignment of the diastereomeric γ-amino alcohols obtained has been established by 1H and 13C NMR studies and unequivocally assigned by their cyclic tetrahydro-1,3-oxazine derivatives 4.
