[reaction: see text] A one-pot InCl(3)-catalyzed Mannich-type reaction was carried out in methanol. High diastereoselectivities and high yields were obtained. In addition, after the reaction was completed, InCl(3) can be recycled and reused without a drop of activity and selectivity.
[reaction: see text] A highly efficient chemical kinetic resolution of bishomoallylic alcohols was developed when the alcohols underwent In(OTf)(3)-catalyzed 3,5-oxonium-ene-type cyclization with steroidal aldehyde 2. Consistently high enantiomeric excess (up to >99%) was obtained.
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.
