  Biomimetic synthesis of (.+-.)-crambines A, B, C1, and C2. Revision of the structure of crambines B and C1

  摘要：

  Crambines A (7) (eight steps, 22%), B (45d) (eight Steps, 19%), C1 (9d) (seven steps, 21%), and C2 (9a) (seven steps, 27%) have been synthesized expediently and stereospecifically by a biomimetic route from methyl acetoacetate. Aminodihydropyrimidines 39 and 40 are formed efficiently from enone ester 36 by a two-step procedure involving addition of O-methylisourea to give methoxydihydropyrimidine 37 followed by displacement of the methoxy group of 37 with ammonia. Hydrogenolysis of 40a and 40d afford crambines C2 and C1, respectively. Mesylation of the alcohol of 39a or 40a followed by Et3N-catalyzed cyclization and hydrogenolysis affords crambine A (7). Aminal formation from 39d or 40d in CHCl3 followed by hydrogenolysis proceeds stereospecifically to provide crambine B (45d). The structure of crambine B has been revised to the stereochemistry shown in 45 and both crambines B and Cl have a seven rather than five-carbon guanidino alkyl chain.

• Synthesis of (±)-Phloeodictine A1
  作者：Bobbianna J. Neubert、Barry B. Snider

  DOI：10.1021/ol034042e

  日期：2003.3.1

  The antitumor antibiotic phloeodictine A1 (2) has been synthesized by a convergent seven-step route in 8% overall yield. The key step was the Eguchi aza-Wittig reaction of 6 to give 13 followed by a retro Diels-Alder reaction to liberate 5. Addition of 11-dodecenylmagnesium bromide to 5 to give 4b, alkylation with 18b, and deprotection completed the first synthesis of 2.
