Theoretical and experimental studies are presented about ?-facial selectivities in Diels-Alder reactions of 5-substituted cyclopentadienes (1).The HOMO and the NHOMO of 1 were readily predicted from the orbital mixing rule to be distorted to favor the syn

5-Phenylthio-1,3-cyclopentadiene reacted with maleic anhydride to give a 4:6 mixture of syn- and anti-attack adducts.In contrast, the selenium isologue, 5-phenylseleno-1,3-cyclopentadiene reacted with dienophiles with remarkable anti-?-facial selectivity
