Abstract

A group of about 30 constitutionally different spiroacetal structures have been characterized from insects1 and represent five spiroacetal systems: 1, 6-dioxaspiro-[4.4] nonane, 1, 6- dioxaspiro [4.5] decane, 1, 6-dioxaspiro-[4.6] decane, 1, 7-dioxaspiro [5.5] undecane, and 1, 7-dioxaspiro [5.6] decane, compounds 1-5 (Chart 1). The characterized spiroacetals are very predominantly odd-numbered in carbon, 1, 2 and only two, 63 and 7, 4 have branched ...
