Catalytic asymmetric dihydroxylations of 1,3-enynes were studied using 9-O-(9′-phenanthryl) dihydroquinidine (PHN-DHQD) 1 and 1,4-bis-(9-O-dihydroquinidine) phthalazine (DHQD2-PHAL) 2. Terminal olefins showed moderate (38-79% ee) and trans-disubstituted olefins high enantioselectivities (73 - 97% ee).
