A certain criticism of the relationship between crystal structure data and stereoelectronic effects persists, based on the following arguments: (a) crystal packing forces and dipolar interactions are dominant in the solid phase; (b) intermolecular interactions are usually neglected in the study of stereoelectronic effects in solution; (c) molecular structures and conformations may differ not only between solution and solid state but also between different crystal forms. See: Thatcher, G. R. J. in ref 15a, Chapter 2 and references therein.

In relation with bicyclic nitrosoacetals, the terms anomeric and pseudoanomeric have been utilized in the literature and may engender a certain controversy. We prefer to unify this terminology, and according to the recent IUPAC recommendations on stereochemistry (Moss, G. P. Pure Appl. Chem. 1996, 68, 2193-2222), such positions may be defined as anomeric. Likewise, the relative stereodescriptors a and β are also utilized by Chemical Abstracts Service to describe the configuration of a cyclic molecule (including polycyclic systems as well) with several stereogenic centers whereby the a side of the reference plane is the side on which the substituent with CIP priority lies at the lowest numbered stereogenic centre. The other side is β.

The inherent complexity of the molecular systems obtained in this work constitutes a challenge to find out a consistent and unequivocal nomenclature. It has been possible to denote these substances in a satisfactory manner after an examination of the nomenclature currently available of 5,5,6-, 5,6,6-, and 5,6,6,6-fused ring systems. See for instance: Comprehensive Heterocyclic Chemistry; Katritzky, A. R., Rees, C. W., Drayton, C. J., Eds.; Pergamon Press: Oxford, 1984; Vol. 8, Part 6 (Ring Index), pp 927-1111. A representation of the different polycyclic systems with the chemical numbering of the atoms has been incorporated as part of the Supporting Information.
