RI_calc = retention indices calculated with respect to a homologous series of n-alkanes on a ZB-5 column. RI_db = retention indices from the databases [29,30,31,32]. ED = enantiomeric distribution (dextrorotatory enantiomer/levorotatory enantiomer). ^a MS(EI): 220(19%), 202(16%), 178(18%), 177(33%), 164(29%), 159(71%), 149(37%), 135(45%), 131(34%), 121(44%), 117(48%), 107(75%), 105(66%), 93(100%), 91(97%), 81(50%), 79(69%), 77(50%), 67(47%), 55(65%), 43(56%), 41(78%).
