Abstract:

H2C:CMeCHO underwent asym. Diels-Alder reaction with cyclopentadiene in presence of the hexanaphthohexaoxadiborabicycloeicosahexaene I to give the (+)-exo-methylbicycloheptenecarboxaldehyde II in 85% yield. I was prepd. from (S)-(-)-2,2'-dihydroxy-1,1'-binaphthyl and H2BBr.SMe2. The structure of I was detd. by x-ray crystallog.
