Chem. Commun., 1997, 1923. Amendment published 2nd February 2000

The structures of compounds 13 and 14 need correction to those shown below. These structures have now been established by X-ray crystal structure analysis, and data have been submitted to the Cambridge Crystallographic Data Centre. The chemical shift for the methine proton in 13 should be reported as δ 4.35.

{Structures 13 and 14}

Crystal data: for 13

C₂₃H₂₇NO₆S₅, M = 573.76, triclinic, space group P-1, a = 8.851(2), b = 9.931(3), c = 16.478(4) Å, α = 83.20(20), β = 75.04(2), γ = 70.00(2)°, V = 1314.1(6) Å³, Z = 2, μ = 0.480 mm⁻¹, T = 150 K. 5709 reflections, 5381 unique (R_int = 0.009).Refinement on F² with all reflections to R1 = 0.0372 and wR₂ = 0.0963. The methylene group of the pyrroline ring is disordered over two sites with occupancies refined to 0.723(9) : 0.277(9).

Crystal data: for 14

C₁₅H₁₂OS₄, M = 336.50, triclinic, space group P-1, a = 8.418(6), b = 8.477(4), c = 11.823(5) Å, α = 85.75(4), β = 78.14(4), γ = 66.94(4)°, V = 759.7(8) Å³, Z = 2, μ = 0.616 mm⁻¹, T = 173 K. 4302 measured reflections, 4041 unique (R_int = 0.017). Refinement on F with 3320 observed reflections to R = 0.0423 and R_w = 0.0501.
