A flexible approach to hexahydronaphthalene-1-carboxylates
摘要:
A flexible approach to hexahydronaphthalene-1-carboxylates based on the Favorskii rearrangement of 1,1-dichloro bicyclo[5.4.0]undec-5-en-2-ones has been devised. 1,1-Dichloro bicyclo[5.4.0]undec-5-en-2-ones can be prepared from readily available cyclohexanones by a short sequence.

A novel intermolecular cross-double-Michael addition between nitro and carbonyl activated olefins has been developed through Lewis base catalysis. The reaction took place with a large group of beta-alkyl nitroalkenes and alpha,beta-unsaturated ketone/esters, producing an allylic nitrocompound in good to excellent yields.
