Synthesis of a Nagilactone Analogue from Totarol
Bendall, Justin G.,Cambie, Richard C.,Rutledge, Peter S.,Woodgate, Paul D.
, p. 1005 - 1019 (2007/10/02)
Totarol (1) has been converted into the nagilactone-A analogue (25) by oxidative decarboxylation of the acid (18).Acid (18) was formed from the benzyl ester (20) after removal of the protecting group by hydrogenolysis, thereby circumventing a difficult hy
