The absolute stereochemistry of Wieland–Miescher ketone analogues bearing an angular protected hydroxymethyl group

Abstract: The Wieland–Miescher ketone analogues (3) and (4), each bearing an angular protected hydroxymethyl group, have been prepared by the amino-acid catalysed cyclisation of their cyclohexane-1,3-dione derivatives (1) and (2); the optical purities and absolute configurations of (3) and (4) have been determined by applying the methoxy (trifluoromethyl)phenylacetate method and the c.d. exciton chirality method, respectively, to their mono-9-ol derivatives.

A useful synthesis of 1,6-dioxo-8a-methyl-trans-δ7-octalin: an isomer of Wieland-Miescher ketone

Abstract: En traitant la cetone de Wieland Miescher par le dimethyl-2,2 propanediol on obtient un monoacetal que l'on reduit par Li/NH 3
