The first preparation of (1S,5R)-(−)- and (1R,5S)-(+)-7-phenyl-3-borabicyclo[3.3.1]non-6-enes and their application for synthesis of chiral cyclohexene derivatives

First synthesis of an optically active derivative of 3-selenabicyclo[3.3.1]nonane

“…6 Heating of the latter with Na 2 Se in boiling EtOH gave the target (1S,5R) 7 phenyl 3 selenabi cyclo[3.3.1]non 6 ene (2) as pale yellow needles. Its struc ture was confirmed by elemental analysis and physico chemical methods.…”
