3-(3,4-Dihydroxyphenyl)-1-methoxy-1-oxopropan-2-aminium chloride
In the title compound, C(10)H(14)NO(4) (+)·Cl(-), the benzene ring makes a dihedral angle of 64.68 (4)° with the methyl-amino-propano-ate unit, which is bonded to the catechol ring via a methyl-ene C atom. A strong intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, O-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds and weak C-H⋯O inter-actions link the mol-ecules into a three-dimensional network.

The title compound, C(24)H(42)N(2)O(7), is a chiral lactam-constrained amino acid with a six-membered ring backbone and isopropyl and tert-butyl ester side chains. The conformation of the six-membered ring can be described as a half chair, with two CH(2) C atoms lying 0.443 (1) and -0.310 (1) Å out of the best plane of the other four atoms (mean deviation = 0.042 Å). Both N atoms are sp(2) hybr...

In the mol-ecule of the title compound, C(29)H(40)O(6), the carbon atom belonging to the propyl chain is connected to two aromatic rings that open up the C(ar-yl)-C-C(ar-yl) angle to 111.5 (1)°. The four-atom -O-CH(2)-C(=O)-O- linkage between the aromatic ring and the tert-butyl group assumes a (-)anti-periplanar conformation for one substituent and a (-)syn-periplanar conformation for the othe...

The asymmetric unit of the title compound, C12H15NO, comprises two sym-metry-independent mol-ecules which differ mainly in the conformations of the tert-butyl groups. The mol-ecules contain an essentially planar five-membered 3-pyrroline ring incorporating a carbonyl substituent (pyrrolinone) which forms part of an isoindolinone skeleton. The planarity of the pyrrole ring is compared to other s...

The title compound, C(10)H(11)Cl(5)O, is a chiral mol-ecule with two stereogenic centres. However, it crystallizes as a racemate. One of enanti-omers reveals the relative configuration (2S*,5R*). The cyclo-hexene ring adopts a half-chair conformation.
