Adipic 3,4-dichloro

Dichlorophenoxy acetic acid (2,4-D) Di(2-ethylhexyl)adipate 2,6-Dichloro-4-phenylenediamine ... 

Various cyclitols (and acyclic polyols) have been desynunetrized by formation of dispoke intermediates. (See for example, Vol. 28, p. 237, ref. 115). L-Chiro-inositol can be converted to the silyl derivative 67 in which the trans-diol units are protected on reaction with l,3-dichloro-l,l,3,3-tetraisopropylidisiloxane (TipsQ). Compound 67 was further converted into conduritol B epoxide and its thioepoxide analogue. The conversion of some tetra-O-substituted myo-inosi-tols into adipic dialdehyde derivatives is mentioned in Chapter IS.
