A simple and efficient stereoselective total syntheses of two natural products (+)-monomorine I and (+)-indolizidine 195B in high yields starting from a readily available alcohol is described. The key step in this synthetic route exploits the judicious use of solvent to enable a closed or open transition state in a nucleophilic addition of Grignard reagent to sulfinimine, giving selective access to two distinct diastereomers required for the formation of the two target natural products.

The Pd(0)-catalyzed allylic cross-coupling of homoallylic tosylate substrates using boronic acids and pinacol esters is reported. The reaction uses 2-(4,5-dihydro-2-oxazolyl)quinoline (quinox) as a ligand and is performed at ambient temperature. The scope of the reaction is broad in terms of both the boronate transmetalating reagent and the substrate and includes secondary tosylates. Mechanistic studies support an alkene-mediated SN2-type stereoinvertive oxidative addition of unactivated primary and secondary alkyl tosylates.

Concise Enantioselective Synthesis of 3,5-Dialkyl-Substituted Indolizidine Alkaloids via Sequential Cross-Metathesis - Double-Reductive Cyclization
Randl, Stefan,Blechert, Siegfried
, p. 8879 - 8882 (2007/10/03)
An efficient stereoselective synthesis of two 3,5-dialkyl-substituted indolizidine alkaloids is reported. The convergent syntheses are based on a novel sequence of a cross-metathesis (CM) reaction of an α,β -unsaturated ketone and a chiral homoallylic amine followed by a domino reaction involving hydrogenation, N-deprotection, and two diastereoselective reductive aminations. Our concept presents one of a few examples of a highly selective CM reaction in the synthesis of a natural product.
