Aldol-type condensation reactions of lithium eneselenolates generated from selenoamides with aldehydes

, p. 2711 - 2716 (2001)
Aldol-type condensation reactions of α-monosubstituted selenoamides with a variety of aldehydes are examined to furnish β-hydroxy selenoamides in good to high yields. The use of selenoamides derived from dibenzylamine exhibits high stereoselectivity. As for the reaction with aliphatic aldehydes selenoamides show better yields and selectivity compared with ordinary amides. Conversion of the resulting β-hydroxy selenoamides to 1,3-amino alcohols is also described.
Titanocene(II)-promoted reactions of thioacetals with ethylene: Selective formation of terminal olefins with one- or two-carbon homologation

Thioacetals are selectively transformed into two types of terminal olefins, one with one-carbon homologation and the other with two-carbon homologation, by treatment with a titanocene(II) species under ethylene. The mode of the reaction is controlled by changing the ligands coordinated to titanocene(II).
Preparation of polysubstituted piperidines via radical cyclization

Polysubstituted piperidines were prepared via radical cyclization of α-aminoalkyl radicals onto unactivated double bonds. [1,2]-aza-Wittig rearrangements were observed when an aryl group was attached to the α-aminoalkyl radical center.
