Studies towards the total synthesis of taxoids: a rapid entry into bicyclo[6.4.0]dodecane ring system. Part 1
摘要:
We report a short and stereocontrolled synthesis of the taxoid BC-subunit (+)-5 embodying the whole carbon framework and most of the required oxygen functionalities for further elaboration. Enantiomeric purity was secured at an early stage by resolution involving derivatization with (S)-2-acetoxypropionyl chloride on (+/-)-10b. (C) 1998 Elsevier Science Ltd. All rights reserved.

We describe an aldol-annelation-fragmentation strategy culminating in the stereoselective synthesis of the whole 20-carbon A-seco taxane framework 1 in only 12 linear steps starting from the two achiral aldol partners 2 and 3. (C) 1998 Elsevier Science Ltd. All rights reserved.
