Allenylsilanes, ene reactions

The allenylsilane ene reaction is also well suited for the synthesis of cyclohexane rings. Jin and Weinreb have described the process of Eq. 13.55 in a synthesis of 5,11-methanomorphanthridine, an Amaryllidaceae alkaloid [64], Conversion of aldehyde 163 to imine 164 with piperonylamine took place in situ. Heating the solution of imine at reflux in mesitylene for 2 h led to cyclization through the conformer shown. The yield of 165 from aldehyde 163 was 66%. [Pg.840]
