A new synthetic method for the preparation of the cholesterol‐lowering drug simvastatin from the naturally occurring lovastatin is reported. The synthesis employs first the protection of the OH group of lovastatin ( 1 ) and then the protection of the lactone CO group to prevent enolization via conversion to the orthoesters 4a and 4b . Alkylation of the 2‐methylbutyrate side chain is then successfully achieved. Removal of the protecting groups affords antihypercholesterolemic agent simvastatin ( 2 ).
