Pd(0) OH OH 203 1. Ireland– Claisen 2. 35 ring, thus completing the elaboration of the fully functionalized decaline system 200. 34). The first synthesis of (−)-perrotinene 202 was reported in 2008 [44]. 35). Alcohol 205 was prepared by Stille coupling between the aryl iodide 203 and the enantiomerically pure vinyl stannane 204. The ensuing, highly stereoselective, Ireland–Claisen rearrangement of the silyl ketene acetal derived from 206 allows a complete chirality transfer and the control of the configuration of the two stereogenic centers in 207.

In both cases, the target was intermediate 145 that has been previously converted to platencin by Nicolaou et al. [30a] and Rawal et al. [30c]. In Lee’s et al. 2]octane moiety was assembled through a radical cyclization/skeletal rearrangement [31]. 23). Mulzer’s et al. 24) [29]. Starting from (−)-perillaldehyde (151), the decaline 152 was prepared. Wittig reaction afforded triene 153, which was submitted to RCM conditions ([Ru]-II, CH2 Cl2 , reflux). RCM completion required more than 24 hours and 8 mol% of catalyst but the yield of 154 was excellent (90%) and no side-products were reported.

31) [41]. 33 Access to anti-Bredt alkenes is possible using an RCM/fragmentation sequence [42]. The strategy has been used for preparing the bicyclic ketone 188 having a structure similar to the AB rings of taxanes 189. 32). Application to the construction of other bridged ring systems has been examined. 33).
