✦ Synopsis

The reduction of alkyl 2,4+lkadienoates, bearing alkyl substituents on the diene system, with sodium dithionite, under phase transfer conditions, gives satisfactory yields of E:i! isomeric mixtures of the corresponding 3_alkenoetes, except in the case Gf-the C-2 substituted substrate which afforded the E-3-alkenoate as the only reduction product.

Selective double bond reduction of unsaturated conjugated ketones has been achieved in excellent yields by use of sodium dithionite in a two phase benzene-water system with Adogen as phase transfer catalyst. However, this reduction was unsatisfactory for hydrophilic ketones; in this case, competitiv
