Abstract

Abstract: Five 14-membered rings of the type 2, 6, 13, 17-tetraheteratricyclo [16.4. 0.07~ 12] docosa-7 (12), 8, 10, 1 (18), 19, 21-hexaene have been synthesized, where the heteroatoms are 3A and 3B,[2, 6, 13, 17-(PPh),], 4,[2, 17-S2-6, 13-(PPh),], 5,[2, 17-(PPh) z-6, 1 3-(NMe),], and 6,[2, 17-(PPh),-6, 1 3-oz]. High-dilution macrocyclization techniques gave these species as colorless crystalline materials in yields ranging from 18 to 45%. Two side products in ...
