Unambiguous assignments of Fleischmann's α,α-bispyrone 3 and Praill's α,γ-bispyrone 6 have been carried out by exploring Lewis acid mediated condensation reactions of α,β-unsaturated carboxylic acids with 4-hydroxy- 2-pyrones. This protocol is shown to be useful for synthesis of a BCDE-ring tetracyclic analog of arisugacin. (C) 2000 Elsevier Science Ltd.

A novel synthetic strategy for obtainment of (±)-3-deoxyradicinin (2) is reported. This synthetic methodology is more efficient than those previously reported in the literature and also shows higher versatility towards the introduction of different side-chains at both C-7 and C-2. The obtained compound (±)-2 shows phytotoxicity against the grass-weed buffelgrass comparable to that of the natural phytotoxin radicinin (1). Therefore, (±)-2 can constitute a more practical synthetic alternative to 1 as bioherbicide for buffelgrass control.
