General Introduction

The spiroacetal, which is more commonly referred to as a spiroketal, is a distinguished architectural feature of many simple and complex natural products with important and varying biological properties. They exist in a number of differing ring arrangements and some of the most abundant include [6,6]-, [6,5]-, and [5,5]-spiroketals. There is also an array of dispiroketal combinations found in many natural products (Scheme 1).
