Addition of aldehydes to cyclohexenylphosphonate carbanions could be e
ffected under very mild conditions and generally gave alpha-addition p
roducts. In almost all cases studied, a mixture of diastereoisomers wa
s obtained. As with alkylation,(1) the addition reactions were governe
d by steric effect's.
