Beschreibung
Zusammenfassung:	6-trans-indol-2-yl-ethenyl)-4-hydroxy-tetrahydro-2H-pyran-2-ones of formula I are obtained by a multi-step reaction involving the procedure: wherein p1 is trisubstituted silyl protective group, and Z is a 2-indolyl radical which may be bear at the 4, 5, 6 and 7-positions up to two substituents such as alkyl, alkoxy, halo and CF3, and at either one the 1 or 3-positions a substituted or unsubstituted phenyl; and at the other an assymetric alkyl, cycloalkyl or aralkyl radical. Compounds I, e.g. (E)-trans-6-[1'-methyl-3'-(4''-fluorophenyl)indol-2'-ylethenyl]3,4,5,6 -tetrahydro-4-hydroxy-2H-pyran-2-one(4R,6S); are useful as anti-atheroselerotic agents.
