The Michael addition of methylvinylketone to β-dicarbonyl compounds prepared from d, l-Δ8a-1-oxo-4β-hydroxy-4bβ-methyl-7-ethyl-enedioxy-4aα, 10aβ-dodecahydro-phenanthrene (Ia) and from the corresponding 1,4-diketone I c has been investigated. Thus from the 2-alkoxyoxalyl compounds III, IVa and b the 2α-alkoxyoxalyl-2 β- (γ-oxo-butyl) derivatives Va, Vb and VIa were obtained in excellent yield.
