Soft carbon nucleophiles intramolecular addition

Suitably semi-protected pyranoses can react with soft carbon nucleophiles generating mixtures of alditols that can undergo elimination of water and intramolecular addition of the 8-hydroxy group to the intermediate alkenes.94,95... [Pg.49]

C. INTRAMOLECULAR ADDITION OF SOFT CARBON NUCLEOPHILES TO CONJUGATED DIENES... [Pg.204]

Activation of Carbon-Carbon r-Bonds. The title compound can form adducts with unpolarized jr-systems, allowing the addition of soft nucleophiles. The addition of /3-dicarbonyls onto alkynes is the most reported instance of this type of reaction, with both intramolecular and intermolecular examples. Welding grade acetylene can even be used as the alkene substrate (eq 35). Imines can also be used as nucleophiles, and then a second nucleophile such as an allylstannane can react with the intermediate iminiumto yield dihydroisoquinolines (eq 36). ... [Pg.359]
