Abstract

1994 reduction, hydrogenation reduction, hydrogenation O 0220 05 -098 Regio-and Stereocontrol in the Reductive Ring Opening of the Spirocyclic Epoxide Derived from the 4-Siloxy-2-cyclopentenone. -The reductive ring opening of the spiro epoxide (I) is performed with various metal hydrides. Depending on the nature of the reagent, the products (II), (IV), or (V) are formed as the main or exclusive product. -(TOMOOKA, K.; ISHIKAWA, K.; AL-MASUM, M.; NAKAI, T.; Synlett (1993) 9, 645-646; Dep.
