Description

Application

Isopropenylmagnesium bromide (iPrMgBr) solution (0.5 M in THF) has been used in the Grignard reaction, a key step the in preparation of zofenoprilat and (S)-(−)-phosphonotrixin. It can also be used for the regioselective ring opening of an optically active epoxy alcohol in the total synthesis of (+)-desepoxyasperdiol.
