Making use of amide activation chiralsynthesis of (+)-(1S,5R)- and (−)-(1R,5S)-3,8-diazabicyclo[3.2.1]octan-2-ones ( and ) has been achieved from L- and D-pyroglutamates, and of (−)-(2R,6S)-, (−)-(2S,6S)-, (+)-(2s,6R)- and (+)-(2R,6R)-2-methyl-1,4-diazabicyclo[4.3.0]nonan-5-ones (a,b,a and b) from L & D-proline methyl esters respectively. The key step of the synthesis involves a stereo-selective catalytic
