T. Bauer et al., EFFICIENT PREPARATION AND X-RAY STRUCTURE ANALYSES OF (2R)-N-PYRUVOYL-BORNANE-10,2-SULTAM AND (2R)-N-(PHENYLGLYOXYLOYL)BORNANE-10,2-SULTAM, Helvetica Chimica Acta, 79(4), 1996, pp. 1059-1066
An efficient synthesis of the two title compounds is reported, as well
as their X-ray crystal-structure analyses. A discussion based on ster
eoelectronic considerations rationalizes the first example of a crysta
lline SO2/C(O) syn-periplanar conformer of a N-acylbornane-10,2-sultam
