Oxazoline N-Oxide-Mediated [2+3] Cycloadditions: New Access to Quaternary Asymmetric Centres
摘要:
Cycloadditions between camphor-derived oxazoline N-oxide I and dipolarophiles 5 or 8 afforded adducts 6 and 9, respectively, with almost complete regio- and stereoselectivity depending on the substitution patterns of the dipolarophiles.
