Ae. Thomas et al., INTRAMOLECULAR ALLYLSILANE-ALDEHYDE CYCLI ZATION IN THE SYNTHESIS OF MEDIUM RING COMPOUNDS, Anales de quimica, 91(3-4), 1995, pp. 206-213
The allylsilane-aldehyde 12a-c, containing a chiral centre. have been
prepared to study their intramolecular cyclization. These compounds cy
clized to 6, 7 and 8 membered rings containing a second chiral centre.
The results indicate that in these cases the chiral centre of the sub
strates 12a-c have very little influence upon the diastereoselectivity
of the cyclization.
