Preferred Label : endo, exo, syn, anti;
IUPAC definition : Descriptors of the relative orientation of groups attached to non-bridgehead atoms
in a bicyclo[ i x.y.z /i ]alkane ( i x /i i y /i > i z /i > 0). If the
group is orientated towards the highest numbered bridge ( i z /i bridge, e.g. C-7
in example below) it is given the description i exo /i ; if it is orientated away
from the highest numbered bridge it is given the description i endo /i . If the group
is attached to the highest numbered bridge and is orientated towards the lowest numbered
bridge ( i x /i bridge, e.g. C-2 in example below) it is given the description i
syn /i ; if the group is orientated away from the lowest numbered bridge it is given
the description i em anti /em /i .;
