摘要：

An improved synthesis of 3,8,12,13,17,22-hexaethyl-2,7,18,23-tetramethyl-sapphyrin (1), is reported. Also presented are flew synthetic procedures for the formation of 8,12,13,17-tetraethyl-7,18-dimethyl-25,29-dioxasapphyrin (2) and 3,7,18,22-tetraethyl-2,8,17,23-tetramethyl-27-thiasapphyrin (3). In addition the syntheses of two completely new heteroatom substituted sapphyrins; 3,7,18,22-tetraethyl-2,8,17,23-tetramethyl-27-oxasapphyrin (4) and 7,18-diethyl-8,17-dimethyl-25,29-dioxa-27-thiasapphyrin (5), are described in detail. The procedures described provide facile routes to representative members of one of the more widely-studied classes of expanded porphyrin macrocycles.
