“…The enantiomeric excess was determined by HPLC analysis (220 nm, 25 °C): t R 13.6 min [(1R,3R)]; t R 16.2 min [(1S,3S)], t R 20.5 min [(1S,3R)]; t R 36.3 min [(1R,3S)] [Chiracel AD-H (0.46 cm × 25 cm) (from Daicel Chemical Ind., Ltd.) hexanes/i-PrOH, 93:7, 1.0 mL/min] to be 96% for the (1R,3R)-diastereomer and 97% for the (1S,3R)-diastereomer; [α] D 24 = +78.7 (c 0.25, CHCl 3 ); 1 Synthesis of (1S,2R,3S)-1,3-Diphenyl-2,3-dihydro-1Hpyrrolo[1,2-a]indol-2-ol (13). 12,14 Martin sulfurane 22 (465 mg, 0.691 mmol, 1.50 equiv) was added to the solution of (1S,3R)-1,3diphenyl-2,3-dihydro-1H-pyrrolo[1,2-a]indol-1-ol 11 (150 mg, 0.461 mmol, 1.00 equiv) in CH 2 Cl 2 (5.0 mL) under a nitrogen atmosphere. The reaction was stirred for 30 min at 23 °C.…”
