摘要：

Configurational assignments are made to some cyclic and acyclic acetals on the basis of the nature of the signals for their O-methylene protons in their pmr spectra. The three known 4,5: 9,10-biscyclohexano-1,3,6,8-tetraoxacyclodecanes are assigned the trans-syn-trans, trans-anti-trans, and cis-anti-cis configurations and the di-(trans-2-hydroxycyclohexyloxy)methanes with mp 80-82° and mp 102.5-103.5° are assigned to the meso form and dl modification, respectively. © 1969, American Chemical Society.
