First [4 + 2] cycloaddition reaction between vinyl Fischer type carbene complexes and chiral 2-amino-1,3-dienes
Abstract
The reaction between 2-aminobuta-1,3-dienes derived from (S)-2-methoxymethylpyrrolidine and vinyl Fischer type tungsten carbenes complexes leads to cyclohexeyl carbene complex derivatives with acceptable yields and good enantiomeric excess.
