Epoxyestersp-menthaniques et pinaniques en milieu basique - Parfum de noix de coco
摘要:
The base-induced isomerization of p-menthane- and pinane-derived epoxy esters was studied. The reaction is dependent on the structure of the terpene compound, the nature of the base, and experimental conditions. Among all the new synthesized compounds, one, 6a, emits a very strong fragrance of coconut. In the structure of this tricyclic lactone, the presence of a methyl substituent is essential.
A highly diastereoselective two-step synthesis of trans-para-menthanic epoxyesters from parent para-menthenic esters is presented. Among bromolactones or bromohydrines obtained with NBS in the first step, only those, which afforded trans-epoxides, reacted.
