Intramolecular TiCl 4 -mediated cyclization reaction of β-hydroxy alkynyl acetals
摘要:
Intramolecular TiCl4-mediated cyclization reaction of 1,1-dimethoxy-3-hydroxy-hex-5-yne derivatives produced anti-1-hydroxy-3-methoxy-cyclohex-5-ene derivatives with high diastereoselectivity via antiperiplanar manner oil pseudo six-membered chair like conformation (transition state A).
