Trehazolin (1) is a trehalase inhibitor produced by Micromonospora coriacea. Biosynthesis of 1 was studied by feeding experiments with a variety of labeled precursors. Feeding experiments with [1-13C]- and [6-13C]-D-glucose revealed that the carbon skeletons of both a glucose residue and a cyclopentane ring moiety in 1 were each derived from glucose, and that C-C bond formation between C-1 and C-5 of glucose occurred during the cyclopentane ring formation. Furthermore, an experiment with [guanidino-13C, 15N2]-L-arginine revealed that two nitrogen atoms and a quaternary carbon atom involved in the aminooxazoline moiety of 1 originated from an amidino group of arginine. Further feeding experiments with [1-2H]-, [2-2H]-, [4-2H]-, [6,6-2H2]- and [1,2,3,4,5,6,6-2H7]-D-glucose as well as [1-13C]-D-fructose showed that deuteriums on C-1, C-3, C-4 and C-6 of glucose were retained during the formation of the cyclopentane ring moiety of 1.

Trehazolin (2) is a specific inhibitor of trehalase, an enzyme that cleaves the reserve carbohydrates of many insects. We describe a short and efficient synthesis of trehazolin (2) and trehazolamine (5) that mimics its hypothetical biosynthesis. Starting molecule for the synthesis of trehazolamine (5) is glucose from which three chiral centers are conserved during the reaction sequence. The remaining two chiral centers of trehazolamine (5) are formed stereoselectively in a reductive cyclization of ketooxime ether 16 and the reduction of oxime ether 18. The overall yield of trehazolamine (5) is 22% over 8 steps from 15. The synthesis of trehazolin (2) from trehazolamine (5) follows a known procedure and is achieved in 63% over 3 steps.

The syntheses and determination of the absolute configuration of trehazolin (1), its aglycon (trehalamine (3), and its aminocyclitol hexaacetate moiety (5) are described. An important intermediate, optically active epoxide 16α, was obtained from an 11-ste

The total synthesis of trehalase inhibitor, trehazolin has been accomplished by coupling the optically active aminocyclopentanepentaol with α-D-glucopyranosylisothiocyanate derivative, followed by subsequent oxazoline-ring formation and removal of the pro
