Functionalized 8-oxabicyclo[3.2.1]octanes (3a-e) were obtained in one stage from vinyl ketones and 5-methylhex-5-en-2-one or 1-phenyl-4-methylpent-4-en-1-one in the presence of the catalytic system [RhCl(C2H4)2]2 - SnCl2.
从乙烯基酮和5-甲基己基-5-en-2-one或1-苯基-4-甲基戊-4-en-1-一步获得官能化的8-氧杂双环[3.2.1]辛烷(3a-e)。一种在催化体系[RhCl(C 2 H 4)2 ] 2 -SnCl 2存在下进行。

Codimerization of vinyl ketones with metallylacetone or metallylacetophenone in the presence of [RhCl(C2H4)2]2-SnCl2 affords substitutedendo-2-acyl-8-oxabicyclo[3.2.1]octanes, the products of the formal [2+2+2] cycloaddition.
