rac-Diethyl 6-hydroxy-4-[(2-hydroxyethyl)amino]-6-methyl-2-phenylcyclohex-3-ene-1,3-dicarboxylate
The title compound, C(21)H(29)NO(6), is chiral with three stereogenic centres. The crystal is a racemate and consists of enanti-omeric pairs with the relative configuration rac-(2R*,3S*,4R*). The ethyl fragment of the eth-oxy-carbonyl group at position 1 is disordered in a 0.60:0.40 ratio. The crystal packing displays inter-molecular O-H⋯O hydrogen bonding. An intra-molecular N-H⋯O hydrogen bon...

In the title compound, C(18)H(22)ClNO(5), the cyclo-hexene ring adopts a distorted half-chair conformation. The mol-ecular structure is stabilized by pairs of intra-molecular N-H⋯O and O-H⋯O inter-actions, generating S(6) motifs. In the crystal, the mol-ecules are linked by inter-molecular C-H⋯O inter-actions, forming centrosymmetric dimers.

interesting results because of the regular arrangement of the molecules in the environment.1–3 We previously reported on the photocycloaddition reaction of 4-methoxy-6-methyl-2-pyrone (1a) (Fig. 1) with maleimide (2) in the solid state to give a highly stereoselective [2 + 2] cycloadduct4 owing to the formation of two sets of 1:1 complex crystals between (1a) and (2) (Fig. 1).5 The crystal show...
