A new method for stereocontrolled synthesis of substituted tetrahydrothiophenes
Ponce, Andres Molina,Overman, Larry E.
, p. 8672 - 8676 (2007/10/03)
A variety of substituted 3-acyltetrahydrothiophenes can be prepared with high stereoselectivity in 50-70% yield by acid-promoted condensation of mercapto allylic alcohols 1 (X = S) with aldehydes and ketones. The mercapto allylic alcohol must be substitut
