A method for producing an optically active trans-vinylsulfide alcohol having the formula:
wherein R1 represents an alkyl group or an aryl group, comprising the step of reducing a trans-vinylsulfide ketone with a borane reducing agent in the presence of an optically active oxazaborolidine and an additive.
annulenoannulenes consisting of two same size nuclei should be fused systems of two diatropic moieties. In order to obtain further information on the nature of annulenoannulene, the synthesis of dibenzo- and benzotrisdehydro[14]annuleno[14]annulenes has been performed.
