NIS-PPh3: a selective reagent for the spiroannulation of o-allyl phenols. Total synthesis of corallidictyal D

J Org Chem. 2013 Sep 20;78(18):9196-204. doi: 10.1021/jo4014047. Epub 2013 Sep 11.

Abstract

Treatment of o-allyl phenols with catalytic NIS-PPh3 affords the corresponding spirodihydrobenzofuran derivatives in high yield with high regio- and total stereoselectivity under mild conditions. These results were utilized to achieve the first total synthesis of the protein kinase C inhibitor corallidictyal D starting from α-ionone.
