Platinum-catalyzed cyclization/[1,2]-alkyl migration/allyl shift/cyclization cascade of epoxy alkynyl allyl ethers: A step-economical route to spirobenzo[h]chromanones

In tandem: A PtI4-catalyzed tandem reaction of epoxy alkynyl allyl ethers involving a cyclization, [1,2]-alkyl migration, O→C allyl shift, aromatic cyclization sequence has been achieved to synthesize spirobenzo[h]chromanones. The reaction simultaneously forms two adjacent stereocenters, one of which is a quaternary carbon atom (see scheme). Copyright
