Description / Table of Contents: Retinoids and Carotenoids, II. - Synthesis of (13Z)-Retinoic AcidsPhosphonium ylides 3 react with (E)-2-methyl-3-(4-methyl-2-oxo-2H-pyran-6-yl)propenal (2) to give 2-pyrone derivatives 4 which undergo ring opening by treatment with sodium tetrahydroborate/potassium hydroxide/methanol affording (13Z)-retinoic acids.

Notes: Phosphoniumylide 3 reagieren mit (E)-2-Methyl-3-(4-methyl-2-oxo-2H-pyran-6-yl)propenal (2) zu 2-Pyronderivaten 4, bei deren Reduktion mit Natrium-tetrahydroborat/Kaliumhydroxid/Methanol unter Ringöffnung (13Z)-Retinoidsäuren 5 entstehen.
