A one-pot, multistep reaction cascade to cyclopentenes from alpha,beta-unsaturated ketones and propargylated carbon acids through a combination of organocatalysis and transition metal ion catalysis is reported; the reaction cascade is simple to perform, occurs under mild conditions and is broad in scope.
据报道,通过有机催化和过渡金属离子催化的结合,一锅多步反应从α,β-不饱和酮和炔丙基化碳酸级联成环戊烯;该反应级联反应易于进行,在温和条件下发生,适用范围广。
