## Abstract The stereochemical course of the intramolecular allylsilane‐aldehyde condensation of **1a** has been investigated. A modest preference for the product arising from a synclinal orientation of double bonds was observed with __Lewis__‐acid catalysts. Cyclization induced by fluoride ion res
C-C bond. When the hydrogens are bent inward, they approach the nodes and their coefficients decrease. This means that CH bonding character is diminished. The opposite is true when the hydrogens are bent back. Not only additional CH but also enhanced CC bonding develops. The energy of the azu orbita
