Enantiomerically pure (R)-2-cyclohexen-1-ol 5 was prepared via lipase- catalyzed enantioselective transesterification of 2-substituted cyclohexanol, and stereospecifically converted to (-)-(2-cyclohexenyl)acetic acid 4. Enantiomerically pure aminoisoquinocarbazole 1 (RS-2135) was synthesized stereoselectively from 4, using an intramolecular Diels-Alder reaction and Curtius rearrangement.

Optically active compounds of formula (I): in which R1 is hydrogen or alkyl; Xband Ybare hydrogen or hydroxy; and Z is -NRaRb, in which Raand Rbare hydrogen, alkyl or hydroxyalkyl,or a cyclic amino group;, and pharmaceutically acceptable salts thereof have enhanced anti-arrhythmic activity and may be prepared by a stereospecific synthesis process.
On Baldwin's Kinetic Barrier Against 5-(Enol-endo)-exo-trigonal Closures: a Comparison of Ionic and Analogous Radical Reactions, and a New Synthesis of Cyclopentanones
Clive, Derrick L. J.,Cheshire, David R.
, p. 1520 - 1523 (2007/10/02)
The kinetic barrier that impedes ionic 5-(enol-endo)-exo-trigonal closures does not play such a dominant role in the case of α-oxo radicals (17); these radicals cyclize directly to cyclopentanones in a process that constitutes a synthetic method for conve
