Yield	Reaction Conditions	Operation in experiment
77%	With lithium borohydride; In tetrahydrofuran; at 0 - 20℃; for 12h;	(±) Compound 4 (5.23 g, 23.85 mmol) was dissolved in anhydrous THF (35 mL) and cooled to 0 C. LiBH4 (1.04 g, 47.70 mmol) was added and the solution was allowed to warm to room temperature and stirred overnight. The reaction was quenched at 0 C with water (20 mL) and then with 10% HC1. The organic layer was separated and the aqueous layer was extracted with EtOAc (4 x 20 mL). The organic layers were combined, dried over MgSO4 and concentrated in vacuo. The crude oil was purified by silica gel column chromatography (cyclohexane/EtOAc, 60:40) to give (±) Compound 5(4.03 g, 77% yield) as a clear oil. (Rf= 0.11, cyclohexane/EtOAc, 50:50).

77.3%	With lithium borohydride; In tetrahydrofuran; at 0 - 20℃;Inert atmosphere;	To a solution of 12-S3 (3.2 g, 13.0 mmol) in THF (45 mL) was added LiBH4 (566 mg, 26.0 mmol) at 0 C. The reaction mixture was stirred under an atmosphere of nitrogen at room temperature overnight. The reactionmixture was quenched with water and extracted with EtOAc (50 mL). The organic phase was washed with brine, dried over anhydrous Na2SO4, and concentrated. The remaining residue was purified by column chromatography on silica gel (eluted with DCMIMeOH = 50:1) to afford the title compound (2.2 g, 77.3% yield) as a yellow oil. LC/MS (ESI) m/z: 220 (M+H).
