    Dictyostatin and its analogs show great promise as new anticancer agents. The present invention provides dictyostatin analogs, synthetic intermediates for the synthesis of dictyostatin analogs, and synthetic methods for the synthesis of such analogs and intermediates. Dictyostatin analogs can have the following structure or its enantiomer wherein R 1 is H, an alkyl group, an aryl group, an alkenyl group, an alkynyl group, or a halogen atom; R 2 is H, a protecting group, an alkyl group, a benzyl group, a trityl group, —SiR a R b R c , CH 2 OR d , or COR e ; R a , R b and R c are independently an alkyl group or an aryl group; R d is an alkyl group, an aryl group, an alkoxylalkyl group, —R i SiR a R b R c or a benzyl group, wherein R i is an alkylene group; R e is an alkyl group, an allyl group, a benzyl group, an aryl group, an alkoxy group, or —NR g R h , wherein R g and R h are independently H, an alkyl group or an aryl group; R 3 is (CH 2 ) n where n is and integer in the range of 0 to 5, —CH 2 CH(CH 3 )—, —CH═CH—, —CH═C(CH 3 )—, or —C≡C—; R 4 is wherein R 23a is H, a protecting group, an alkyl group, a benzyl group, a trityl group, —SiR a R b R c , CH 2 OR d , or COR e ; R 23b is H, a protecting group, an alkyl group, a benzyl group, a trityl group, —SiR a R b R c , CH 2 OR d , or COR e , or R 23a and R 23b together form a portion of six-membered acetal ring incorporating CR t R u ; R t and R u are independently H, an alkyl group, an aryl group or an alkoxyaryl group; and R 5 is H or OR 2b , wherein R 2b is H, a protecting group, an alkyl group, an aryl group, a benzyl group, a trityl group, —SiR a R b R c , CH 2 OR d , or COR e ; provided that the compound is not dictyostatin 1.
    Dictyostatin及其类似物作为新的抗癌剂表现出极大的潜力。本发明提供了Dictyostatin类似物,用于合成Dictyostatin类似物的合成中间体以及合成此类类似物和中间体的合成方法。Dictyostatin类似物可以具有以下结构或其对映体,其中R1为H、烷基、芳基、烯基、炔基或卤素原子;R2为H、保护基、烷基、苄基、三苄基甲基基、-SiRaRbRc、 ORd或CORe;Ra、Rb和Rc独立地为烷基或芳基;Rd为烷基、芳基、烷氧基烷基、-RiSiRaRbRc或苄基,其中Ri为烷基;Re为烷基、烯丙基、苄基、芳基、烷氧基或-NRgRh,其中Rg和Rh独立地为H、烷基或芳基;R3为(CH2)n,其中n在0到5的整数范围内,- CH(CH3)-、-CH═CH-、-CH═C( )-或-C≡C-;R4为其中R23a为H、保护基、烷基、苄基、三苄基甲基基、-SiRaRbRc、 ORd或CORe;R23b为H、保护基、烷基、苄基、三苄基甲基基、-SiRaRbRc、 ORd或CORe,或R23a和R23b一起形成包含CRtRu的六元缩醛环的一部分;Rt和Ru独立地为H、烷基、芳基或烷氧基芳基;R5为H或OR2b,其中R2b为H、保护基、烷基、芳基、苄基、三苄基甲基基、-SiRaRbRc、 ORd或CORe;但化合物不是Dictyostatin 1。
