A general approach to 1,6,7-trihydroxyindolizidin-8-carboxylates is illustrated through the synthesis of a c-lactone in an enantiopure form in seven steps starting from (3S)-3-t-butyloxy-1-pyrroline N-oxide and the acetonide of (2E,4S)-4,5-dihydroxy-2- pentenoic acid derived from (S)-malic acid and mannitol, respectively. The process was completely stereoselective and allowed the total control of the relative and absolute configuration of the five contiguous stereocentres of the product.

Abstract

A general approach to 1,6,7-trihydroxyindolizidin-8-carboxylates is illustrated through the synthesis of a c-lactone in an enantiopure form in seven steps starting from (3S)-3-t-butyloxy-1-pyrroline N-oxide and the acetonide of (2E,4S)-4,5-dihydroxy-2- pentenoic acid derived from (S)-malic acid and mannitol, respectively. The process was completely stereoselective and allowed the total control of the relative and absolute configuration of the five contiguous stereocentres of the product.
