Lipase catalyzed regioselective lactamization as a key step in the synthesis of N-Boc (2R)-1,4-oxazepane-2-carboxylic acid

A synthesis of N-Boc (2R)-1,4-oxazepane-2-carboxylic acid was developed in 39% yield over seven steps starting from methyl (2R)-glycidate. The key step was a lipase-catalyzed regioselective lactamization performed using SpinChem® rotating bed reactor that simplified work up and recycling of the enzyme.
