X-ray analysis of products 3aa showed that main product has anti-configuration.

Typical Procedure for 1,2-Addition of Alkynes to Imine in the Presence of LiHMDS. Phenylacetylene 2a (60 mg, 0.6 mmol) was added to the mixture of LiHMDS (0.6 mmol, 1 M solution in THF) and n-hexane (3.0 mL) at -78 °C. 2-Methyl-N-(pentylidene)-propan-2-sulfinamide 1c (57 mg, 0.3 mmol) was added subsequently and the resulting mixture was stirred for 30 min at the same temperature. Then the reaction mixture was warmed to r.t. and stirred till complete consumption of substrate (monitored by TLC). The reaction mixture was quenched with 5 mL of sat. NH₄Cl aq solution. The aqueous layer extracted with CH₂Cl₂ (3 × 10 mL). The combined organic layer was dried over anhyd Na₂SO₄, filtered, and concentrated in vacuo. The crude product was purified by flash column chromatography on silical gel and gave propargylamine 3ca; 66 mg, 76% yield. ¹H NMR (CDCl₃/TMS): δ = 0.93 (t, J = 7.2 Hz, 3 H), 1.24 (s, 9 H), 1.34-1.53 (m, 4 H), 1.76-1.85 (m, 2 H), 3.43 (d, J = 6.0 Hz, 1 H), 4.25 (dd, J = 6.0, 13.5 Hz, 1 H), 7.27-7.32 (m, 3 H), 7.42-7.46 (m, 2 H). ¹³C NMR (75 MHz, CDCl₃): δ = 13.98, 22.23, 22.50, 27.72, 36.57, 48.07, 56.06, 84.68, 89.05, 122.59, 128.16, 128.26, 131.70; IR (film): ν = 3249, 1491, 1045 cm^-1; MS (EI): m/z (%) = 234 (1.07) [M - 57]⁺, 189 (28), 171 (12), 57 (100).
