(6R,7R)-7-benzyloxycarbonylamino-2,2-dimethyl-1-aza-3-oxabicyclo[4.2.0]octan-8-one → (6R,7R)-7-amino-2,2-dimethyl-1-aza-3-oxabicyclo[4.2.0]octan-8-one

Participants

Reaction Steps

A mixture of (6R,7R)-7-benzyloxycarbonylamino-2,2-dimethyl-1-aza-3-oxabicyclo[4.2.0]octan-8-one (748 mg) and 10% palladium charcoal (180 mg) in ethyl acetate (15 ml) was stirred under a hydrogen atmosphere for 1.5 hours at ambient temperature. The mixture was filtered and the filtrate was evaporated in vacuo to give (6R,7R)-7-amino-2,2-dimethyl-1-aza-3-oxabicyclo[4.2.0]octan-8-one (382 mg) as a crystalline solid.
