Syn/anti is a notation used in these works to distinguish the two facial diastereoisomers and is also applied in the present paper. Thus, syn facial diastereoselection is referred to the attack of the diene on the π-face of the double bond marked by the black arrow, assuming a conformation for the dioxolane ring as represented in the figure. Anti orientation is stated by the white arrow to occur by the opposite side of the plane. Although we reported in reference 12a that such a conformation involves, indeed, an energy maximum, this representation is useful to unify the nomenclature. (Metrix Presented)
