The title spirocarbopeptoid, C 11 H 13 N 2 O 5 , was prepared from l-fucose in a sequence that gave this and another anomer. The crystal structure determination removes ambiguities in the synthetic sequence.

The title compound, C~25~H~24~N~2~O~3~S~3~, was crystallized from a methanol–acetone mixture. The monoclinic structure features one molecule in the asymmetric unit. The crystal packing is stabilized by π stacking.
In the title cocrystal, 0.893C 19 H 20 O 4 Á0.104C 18 H 17 ClO 3 Á-0.003C 17 H 14 Cl 2 O, the crystal packing is stabilized by weak intermolecular C-HÁ Á ÁO and C-HÁ Á Á interactions.
In the title compound, C 22 H 23 BF 2 N 2 O, the styrene and borondipyrromethene (BODIPY) fused-ring fragments are almost coplanar. Short C-C bond lengths suggest some electronic conjugation between the two systems.
