Title:
エクテナサイジン類の全合成方法、エクテナサイジン類に類縁構造を持つ前記全合成用中間体化合物類、及び該中間体化合物類の合成方法
Document Type and Number:
Japanese Patent JP4208469
Kind Code:
B2
Abstract:
Intermediates (I) for the total synthesis of ecteinascidin compounds are new having the 10 membered ring structure of ecteinascidins with a 4-position thioether group and trichloroethoxycarbonyl (Troc) substituent as R 2in the 12-N position. Intermediates of formula (I) for the total synthesis of ecteinascidin compounds are new, having the 10 membered ring structure of ecteinascidins with a 4-position thioether group and trichloroethoxycarbonyl (Troc) substituent as R 2in the 12-N position. [Image] Y : O or NH; X 2-X 4H, 1-4C alkyl, alkoxyalkyl, allyl, alkylsulfonyl or arylsulfonyl; R 1, R 4H or 1-4C alkyl; R 2alkoxycarbonyl, haloalkoxycarbonyl, lower alkylsulfonyl or arylsulfonyl (sic; in description above R 2= Troc); and R 3CN or OH. Independent claims are also included for (1) intermediates of formula (II) for the total synthesis of ecteinascidin compounds having the skeletal pentacyclic ring structure of ecteinascidins, with a 4-position OH group and Troc substituent as R 2in the 12-N position (sic; as in (I) R 2not defined as Troc); (2) intermediates of formula (III) for the total synthesis of ecteinascidin compounds which forms the skeletal pentacyclic ring structure of ecteinascidins when the 10-position H is replaced by a bond; (3) intermediates for compound (III) of formula (IV) and (V); and (4) the preparation of an ecteinascidin intermediate of formula (IA) from (II).
