An efficient enzymatic process has been developed to resolve a diastereomeric mixture of racemic ethyl bicyclo[3.2.0]hept-6-ylidene-acetate (1). Using 40% acetone, not only was the enantioselectivity of Candida antarctica lipase B (CAL-B) significantly improved to E > 200 from E = 2.7, remarkably the enzyme is able to maintain low diastereoselectivity for the Z (cis)- and E (trans)-isomers leading

Synthesis of a number of bicyclic five-membered ring derivatives of gabapentin led to the identification of two compounds, (-)-(11A) and (20A) which both had an excellent level of potency against alpha(2)delta and were pro. led in an in vivo model of neuropathic pain.
