- PublicationMétadonnées seulementPreparation of N-alkylketene-N-butadienyl-N,O-silyl acetals(1996)
;Franz, Andreas ;Eschler, Pierre Yves ;Tharin, Manuel; The synthesis of a series of dienamides 5a-j using Oppolzer's method is described. Using Rathke's method the ketene N,O-silyl acetals 6a-j can be obtained in good yield from the corresponding dienamides. The ketene acetals are obtained free of base and free of salts. They are stable and can be stored at - 20 degrees C. The new dienes are useful reagents for tandem reactions. - PublicationMétadonnées seulementThe preparation and the cascade reactions of N-butadienyl-N-alkylketene N,O-tert-butyldimethylsilyl acetals(: Pergamon-Elsevier Science Ltd, 1996)
;Franz, Andreas ;Eschler, Pierre Yves ;Tharin, ManuelThe preparation of N-butadienyl-N-alkylketene N,O-tert-butyldimethylsilyl acetals (11a-d) from readily available starting materials is described. The cascade Diels-Alder reaction followed by acylation of these ketene acetals yields bicyclic and tricyclic products 7, 13a,b and 14c,d with high diastereoselectivity.
