These results have important implications for strategies designed to boost antimicrobial T-cell-mediated immunity in transplant recipients.Lawsone aldehydes were directly transformed into the biologically important, unique carbon skeleton of chiral methanobenzo[f]azulenes/methanodibenzo[a,d][7]annulenes in high dr and ee and in very good yields by using quinine-thiourea-catalyzed tandem Wittig/intramolecular Michael/intramolecular aldol reactions. This asymmetric catalytic tandem protocol will be highly useful because these final mole
