Synthetic studies towards gambierol. Part 2: Synthesis of the EFGH ring segment

✍ Isao Kadota; Chie Kadowaki; Hiroyoshi Takamura; Yoshinori Yamamoto 📂 Article 📅 2001 🏛 Elsevier Science 🌐 French ⚖ 69 KB

The EFGH ring segment of gambierol was synthesized from 2-deoxy-D-ribose in 40 steps. The present synthesis includes a SmI 2 -mediated reductive cyclization and a Pd-catalyzed coupling of enol triflate with a zinc bis-homoenolate as key steps.

Synthetic study of aquayamycin. Part 2: Synthesis of the AB ring fragment

✍ Hiroki Yamaguchi; Tadayoshi Konegawa; Mitsujiro Tanabe; Takeshi Nakamura; Takash 📂 Article 📅 2000 🏛 Elsevier Science 🌐 French ⚖ 64 KB

A highly oxygen-functionalized cyclohexenone 2, the AB ring fragment for the aquayamycin synthesis, was efficiently synthesized via stereoselective addition of allylzinc bromide to ketone 3a which, in turn, was available from the optically pure cyclohexane 1,2,3-triol derivative 5.

Synthetic Studies towards Halichondrins: Synthesis of the C.27–C.38 Segment

✍ Thomas D. Aicher; Keith R. Buszek; Francis G. Fang; Craig J. Forsyth; Sun Ho Jun 📂 Article 📅 1992 🏛 Elsevier Science 🌐 French ⚖ 277 KB

An efficient synthesis of the C.27-C.38 segment of halichondrins is accomplished, using the Ireland-Claisen rearrangement, Ni(ll)lCr(Il)-mediated coupling and Michael reactions as the key steps.
