Abstract
SB 222618 (1) has been a target of synthetic chemists at SmithKline Beecham owing to its potential PDE IV 1 inhibitor activity against inflammatory diseases such as asthma. Apart from its biological activity, this cyclohexanol provided the opportunity to explore the non-obvious construction of the quaternary C 4 of 1 whose retrosynthesis is shown below (Scheme 1). ... As depicted in Scheme 1, SB 222618 (1) could be obtained via the Sonogashira 2 coupling protocol between ...
