(2S,NS)-N-Allyl-N-benzyl-1-hydr-oxy-3-(4-hydroxy-phen-yl)-N-methyl-propan-2-aminium bromide.

ABSTRACT: The title compound, C(20)H(26)NO(2) (+)·Br(-), is an N-chiral quaternary ammonium salt synthesized from (2S*)-N-benzyl-N-methyl-tyrosine methyl ester. The dihedral angle between the phenyl ring and the benzene ring is 11.61?(19)°. In the crystal structure, the allyl group is disordered over two positions with site occupancy factors of ca 0.8 and 0.2. The bromide anion links to the quaternary ammonium cations via O-H?Br hydrogen bonding. An intramolecular O-H?Br hydrogen bond is also observed.

The title compound, C(20)H(26)NO(2) (+)·Br(-), is an N-chiral quaternary ammonium salt synthesized from (2S*)-N-benzyl-N-methyl-tyrosine methyl ester. The dihedral angle between the phenyl ring and the benzene ring is 11.61 (19)°. In the crystal structure, the allyl group is disordered over two positions with site occupancy factors of ca 0.8 and 0.2. The bromide anion links to the quaternary ammonium cations via O-H⋯Br hydrogen bonding. An intramolecular O-H⋯Br hydrogen bond is also observed. ...[more]
