✦ Synopsis

Pd(O)-catal)zed a~,lation of the aryl-substituted a-allenic alcohols with ,~vpen, alent iodonium salts afforded substituted trans-epoxides Alternatively. arylation ~[ the alkyl-substituted a-a/lenic alcohols in the presence of K2COj afforded syn-d~ol cyclic carbonates and trans-epoxides in the
