Convenient syntheses of 5-substituted 2- hydroxybenzoates and related reactions

Abstract
The enamine aidehydes RC(CHNMe2)CHO (R = Et or Ph) were condensed with the bis-enolate CH2 C(O)CHC(O)OEt to give the title aromatic compounds. Thus these products are available from the acetals R1CH2CH(OR2)2(R1= R2= Et; R1= Ph, R2= Me) in two steps. The Vilsmeier formylation of several derivatives of butanal was examined.
