A direct asymmetric hydroxyamination reaction of aldehydes with nitrosobenzene was found to be catalyzed by the novel axially chiral secondary amine catalyst (S)-1d. The resulting optically enriched hydroxyamination products were readily converted to beta-amino alcohols or 1,2-diamines in one pot.
Sleeve lung resection can achieve local tumor control and long-term survival with low mortality and few anastomotic complications. Nodal status significantly affects long-term survival. Limited and extended resections are also feasible with local and long-term results comparable to those of standard sleeve lobectomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
