(1S,2R,8R)-11-Amino-2,2-dichloro-3,7,7,10-tetramethyltricyclo[6.4.0.01,3]dodec-10-en-9-one

Abstract

The title compound, C16H23Cl2NO, crystallizes in the monoclinic space group P21 with two independent molecules (A and B) in the asymmetric unit. They have essentially the same conformation. Each molecule is built up from fused six- and seven-membered rings and an additional three-membered ring. The six-membered ring has an envelope conformation, with the C atom belonging to the three-membered ring forming the flap, while the seven-membered ring displays a boat conformation. In the crystal, molecules are linked into chains propagating along the a-axis direction by N—H...O hydrogen bonds.
