DBU/H 2 O: a probing medium for diastereoselective Diels–Alder reactions of (arylvinyl)cyclohex-2-en-1-one dienes with a symmetrical trans dienophile
M. Saeed Abaee, Zahra Shabani, Mohammad M. MojtahediA DBU/H 2 O medium was used to assess the stereoselectivity of the DA reactions of isophorone-derived dienes with DMF, giving the major endo adduct only (19 : 1). In contrast, the thermal reaction in PhMe produced a 5 : 1 mixture of two adducts.
