A new ruthenium complex catalyzes the amination of primary and secondary alcohols and the regioselective mono- and sequential diamination of diols via the borrowing hydrogen pathway. Several variations on new intra- and intermolecular cyclizations of aminoalcohols, diols, and diamines lead to heterocyclic ring systems.
3-Anilino-1-propanol derivatives 4a–c, 5a–c, 6a–c containing primary, secondary, and tertiary alcohols and PhNH, PhNMe, and (Ph)2N were prepared and subjected to gas-phase pyrolysis in a static reaction system. The pyrolytic reactions were homogeneous and followed a first-order rate equation. Reactions took place by retro-ene process, with the exception of compounds 5a and 5b. Analysis of the pyrolysate

hydroalkoxylation of allylic alcohols catalyzed by a simple catalyst Y(CH2SiMe3)3(THF)2 has been developed, providing a variety of γ-amino and γ-alkoxy alcohols in good yields under mild conditions. Moreover, this protocol is applied to the synthesis of drug molecules Propipocaine and Proroxan. The rare-earth catalyst features readily available, wide substrate compatability, exclusive anti-Markovnikov selectivity
