Suprafacial rearrangements, defined

Table 4 shows examples for the sulfoxide rearrangement of different 2-cycloalkenyl sulfoxides 22"32-44-76 78, mostly obtained by oxidation of a stereochemically defined precursor (diastereomerically or enantiomerically pure, entries 3-82 t 2, 1076). In all cases complete chirality transfer was observed due to the suprafacial character of the rearrangement.
