Simvastatin is an active synthetic analogue of Lovastatin. Most of the synthetic processes start with either Lovastatin or it's derivatives. Here are important ones:

Simvastatin semi-synthesis: Org Proc Res Dev 1999, 3(6), 476-479

Simvastatin semi-synthesis: Scheme 1 (J Org Chem 1991, 56(16), 4929-4932) (Not favoured as final yield is only 48%. Moreover, Lovastatin appears as major impurity with the final product)

Simvastatin semi-synthesis: Scheme 2 (J Org Chem 1991, 56(16), 4929-4932) (Yield of 91%; commerically preferred route)
