Utilization of industrial waste materials. Part 14.† Synthesis of β-amino alcohols and thiols with a 2-azabicyclo[3.3.0]octane backbone and their application in enantioselective catalysis
New, chiral β-tert-amino tert-alcohols have been synthesized from the enantiomerically pure sec-amine (all-R)-1b via the new glycine, alanine and phenylglycine derivatives 2–6. Grignard additions to these esters provided the new rigid amino alcohols 7–11 in fair yields. The absolute configurations of the stereogenic centers, which arose during the alkylation step, were assigned by an independent route
