Description
Abstract Diastereoselective construction of the 19- epi -C 18 –C 25 segment of (−)-lasonolide A was achieved using a 5- exo -trigonal mode of radical cyclization for the creation of the contiguous quaternary and tertiary stereogenic centers at C 22 and C 23 as the key reaction step. During the dehydration stage, it was found that an unusual inversion of configuration took place.
