A continuous Michael and aldol coupling of α,β-enones catalyzed by iridium complexes

Ir[(COD)(PPh3)2]OTf activated by H2 molecule catalyzes Michael-type coupling of α,β-enones with enoxysilanes to give 1,5-dicarbonyl compounds after the subsequent protodesilylation. An identical catalyst system makes it possible to attain a continuous Michael and aldol modification toward α,β- enones in a one-pot operation. (C) 2000 Elsevier Science Ltd.

Δ3-DIHYDROPYRANS AND TETRAHYDROPYRANS BY REDUCTION OF PYRYLIUM SALTS WITH SODIUM BOROHYDRIDE IN ACETIC ACID

The major reduction products with triacetoxyborohydride (NaBH4 in AcOH) of 2,4,6-trisubstituted pyrylium salts bearing alkyl substituents in the 2- and/or 6-position are the Δ3-dihydropyrans with cis 2- and 6-substituents and all-cis-2,4,6-trisubstituted tetrahydropyrans. Δ3-dihydropyrans are shown to be formed via 2H-pyrans by a 1,4 reduction while tetrahydropyrans result from 4H-pyrans by reduction of both enol-ether double bonds.
