โœฆ Synopsis


Double asymmetric induction has been used to increase the diastereoselectivity of the dihydroqlation of the allylsilane +(II) wing dihydroquinidim p-chlorobenmate AS catalyst.

The ester-allylsilanes ( 5) and ( 6) and the acid-allylsilane (7) react stereoselectively with m-CPBA; the major product from ( 5) and ( 7) was the y-lactone (4), whereas (6) failed to undergo lactonisation, the major product in this case was the P,wpoxy-silane (12).

A new double asymmetric induction in carbon-carbon bond formation is -achieved by the use of palladium chiral complexes in the alkylation of chiral Schiff bases1 derived from glycine. High diastereoisomeric excesses are obtained (90-999) using N.N-cyclohexylsulfamoylisobornyl derivatives and DIOP as
