Synthesis of a 13C-labelled seed-germination inhibitor (3,4,5-trimethylfuran-2(5H)-one) for the mode of action elucidation

Abstract: It has been found that the butenolide 3,4,5-trimethylfuran-2(5H)-one, isolated from plant-derived smoke, efficiently inhibits seed germination and significantly reduces the effect of the highly active germination promotor karrikinolide (KAR

Propenals substituted with a dithiane ring and processes for the preparation of these propenals

Propenals of formula: STR1 in which formula R is H or a C1 -C4 thioalkyl radical, the dithiane ring being at the cis position in relation to the aldehyde function when R is H and at the trans position when R is a thioalkyl radical. The invention also relates to two processes for the preparation of these propenals.
