Abstract

The total synthesis of (E)‐Suberenol (1) was carried out under the conditions of palladium‐catalysed Heck condensation. Two other new coumarins, (E)‐7‐methoxy‐6‐(3‐methyl‐1,3‐butadienyl)coumarin [(E)‐suberodiene] (3) and (E)‐7‐methoxy‐6‐(3‐methyl‐1‐butenyl)coumarin [(E)‐suberenene] (4) and cyclobisuberodiene (2) were synthesised from (E)‐suberenol.

A new synthetic approach is described for building the coumarin scaffold through the Lewis acidpromoted cyclization of novel aryl 3-(dimethylamino)prop-2-enoates 2a -2f. The latter precursors were prepared via aminomethylenation of the corresponding aryl acetates 4a -4f with the Bredereck reagent. T
