资源简介:
A new
class of highly acidic confined imino-imidodiphosphate (iIDP) Brønsted acids catalyze the asymmetric Prins
cyclization of both aliphatic and aromatic aldehydes. Diverse functionalized
4-methylenetetrahydropyrans are obtained in good to excellent yields
and with good to excellent regio- and enantioselectivities. Our iIDP catalysts provide an efficient and scalable enantioselective
approach to various fragrances, including rose oxide and doremox.
