Abstract
An improved synthetic procedure for the intramolecular ketene [2+2] cycloaddition was developed for the preparation of 1‐heteroatom‐substituted bicyclo[2.1.1]hexan‐5‐ones. It was found that the use of the Mukaiyama reagent (2‐chloro‐N‐methyl‐pyridinium iodide) was key to efficiently generate the α‐heteroatom substituted homoallyl ketene intermediate for the cycloaddition reaction. The synthetic utility of the resulting bicyclic ketone was demonstrated through the preparation of a saturated variant of vortioxetine.
期刊介绍：
Organic chemistry is the fundamental science that stands at the heart of chemistry, biology, and materials science. Research in these areas is vigorous and truly international, with three major regions making almost equal contributions: America, Europe and Asia. Asia now has its own top international organic chemistry journal—the Asian Journal of Organic Chemistry (AsianJOC)
The AsianJOC is designed to be a top-ranked international research journal and publishes primary research as well as critical secondary information from authors across the world. The journal covers organic chemistry in its entirety. Authors and readers come from academia, the chemical industry, and government laboratories.
