Web(±)-daphgraciline. After establishing the [6-7-5-5] ring system of intermediate J, Benkeser reduction cleaved the ether bridge and deprotected the tosyl amide. The free amine was methylated and the diol closed to epoxide L. A reductive epoxide opening– cyclization cascade forged the lactone in M and paved the way to (±)-daphgraciline. O O ...
