A stereoselectivetotalsynthesis of the cytotoxic natural products tubulysin U, tubulysin V, and its unnatural epimer epi-tubulysin V, is reported. Simplified analogues containing N,N-dimethyl-d-alanine as a replacement for the N-terminal N-Me-pipecolinic acid residue of the tubulysins are also disclosed. Biologicalevaluation of these natural products and analogues provided key information with regard
报道了细胞毒性天然产物微管溶素 U、微管溶素 V 及其非天然差向异构体表观微管溶素 V 的立体选择性全合成。含简化类似物Ñ,Ñ二甲基d丙氨酸作为N-末端的替代Ñ微管溶素的-Me-2-哌啶酸残基也被公开。这些天然产物和类似物的生物学评价提供了关于抗增殖活性和微管蛋白聚合抑制的结构和立体化学要求的关键信息。
Cytotoxicity and actin-depolymerizing activity of aplyronine A, a potent antitumor macrolide of marine origin, and its analogs
Artificial analogs of aplyronine A (1), a potentantitumor macrolide, were synthesized and structure–activity (cytotoxicity and actin-depolymerizing activity) relationships were investigated; the side-chain in 1 was found to play a key role in both biological activities.
A method for synthesizing levomethadone hydrochloride including producing (R)-2-(dimethylamino)propan-1-ol by reducing N,N-dimethyl-D-alanine using borax, forming (R)-1-chloro-N,N-dimethylpropane-2-amine hydrochloride by chlorinating the (R)-2-(dimethylamino)propan-1-ol, synthesizing levomethadone nitrile hydrochloride by mixing the (R)-1-chloro-N,N-dimethylpropane-2-amine and diphenylacetonitrile with potassium t-butoxide and producing levomethadone hydrochloride by exposing the levomethadone nitrile hydrochloride to a Grignard reagent.

following optically active analogs of acetylcholine were studied: 3 (a)-trimethylammonium-2(a)-acetoxy-trans-decalin iodide, threo- and erythro-alpha, beta-dimethylacetylcholine iodide, alpha-methylacetylcholine, and beta-methylacetylcholine. Evidence that the optimum dihedral +N-C-C-O angle in the transition state for acetylcholinesterase hydrolysis of acetylcholineanalogs is positive and anticlinal
