Prostaglandins and Prostaglandin Intermediates. 22 - Synthesis of a Stable Prostacyclin Analogue

Theil, F.,Costisella, B.,Hauser, A.,Schick, H.,Schwarz, S.

, p. 766 - 774 (2007/10/02)

An industrially available prostaglandin intermediate is converted into a new prostacyclin analogue with a cyclic ether instead of the unstable enol ether system.For the construction of the modified alkyl side chain two subsequent Horner olefinations are used.This reaction sequence includes a new methodology for the conversion of an aldehyde into a β,γ-unsaturated carboxylic acid by a three-carbon elongation.
