The expedient enantioselective synthesis of 5 bisabolane sesquiterpenes has been achieved using a common, one-pot lithiation-borylation reaction of secondary benzylic carbamates and either protodeboronation or oxidation to give the natural products in fewer than 5 steps, with high yield and >94 : 6 er.

A short and efficient, high-yielding enantioselective total synthesis of the marine natural product (−)-curcuquinone 1 is reported involving a regioselective [3 + 2 + 1]-benzannulation reaction as the key step. Additionally, this strategy allows the isolation of curcuhydroquinone monomethyl ether 9 as an intermediate of the benzannulation reaction and its subsequent further protection toward diversified
