An Approach for General Synthesis of Biphenyl Neolignans by the Reaction of 1-Oxaspirodeca-6,9-diene-2,8-dione with the Grignard Reagent and Synthesis of Magnaldehyde B

An approach for general synthesis of biphenyl neolignans by the reactionof 1-oxaspiro-deca -6,9-diene-2,8-dione (3) (quinol-lactone) with the Grignard reagent 4 was explored.Among the biphenyl derivatives 6,8 and 9 thus obtained, 6 was transformed to magnaldehyde B (2b) in three steps.Keywords---biphenyl neolignan; synthesis; magnaldehyde B; quinol-lactone; Grignard reagent
