Intramolecular stereoselective protonation of aldehyde-derived enolates
Kena-diba, Anastasie,Noll, Claudia,Richter, Michael,Gieseler, Marc Timo,Kalesse, Markus
supporting information; experimental part, p. 8367 - 8369 (2010/12/25)
Picking sides: Asymmetric protonation of the titled compounds poses a most significant challenge and has been addressed by taking advantage of internal protonation and subsequent hemiacetal formation to avoid epimerization (see scheme). The substrates employed in these transformations can be easily accessed through a sequence of vinylogous aldol reactions with subsequent conjugate reductions.
Stereochemistry of the reaction of Si-phenyl silenes with butadienes: Elaboration of the silacycloadducts to provide a novel route to substituted lactones
Sanganee, Mahesh J.,Steel, Patrick G.,Whelligan, Daniel K.
, p. 2393 - 2402 (2007/10/03)
Silenes generated through a silyl-modified Peterson olefination procedure can be trapped with a range of alkyl butadienes via a [4 + 2] cycloaddition pathway to afford silacycles accompanied by variable amounts of competing ene, [2 + 2] and silene dimer b
