Synthesis of Tertiary and Quaternary Stereogenic Centers: A Diastereoselective
Reaction Sequence Combining Mukaiyama and Free Radical-Based
25- 060 Tandem
Allylation. — Mukaiyama reaction of the aldehydes (I) and (VIII) results in stereoselective formation of anti,anti-adducts of type (III) or syn,syn-adducts of type (IX) depending on the Lewis acid used. Lewis acid mediated radical allylation of these adducts
proceeds with high diastereoselectivity giving the corresponding 2,3-anti products predominantly. In some cases, a one-pot tandem sequence is possible avoiding isolation of
aldolization products. — (CARDINAL-DAVID, B.; GUERIN, B.; GUINDON*, Y.;
