Abstract
A new synthetic strategy for C7-carbasugars is developed via an intramolecular Morita-Baylis-Hillman reaction, in which a substituted dial precursor prepared from d-mannose cyclizes smoothly in the presence of DMAP to afford polyhydroxylated cyclohex-1-enecarbaldehyde with good yield. By employment of the cyclization products as key intermediates, the first syntheses of carbasugar ester 1 and epicorepoxydon A, as well as practical syntheses of epoxydines B and C, (-)-MK7607, (-)-streptol, and (-)-gabosine E are achieved.

Abstract
Gabosines and their natural analogues, belonging to C7 carbasugars, have attracted great attention in synthesis due to their rich structural variety and promising biological activities. A new diversity-oriented approach for the gabosine-type carbasugars based on a tunable regioselective aldol cyclization of flexible precursor 2 is explored. Two cyclization modes (A and B) of the precursor can be well controlled by switching promoters to selectively produce two resulting cyclohexa(e)nones 3 and 10, both of which are versatile intermediates for various C7 carbasugars. After the conversion of 3 to eight natural carbasugars, the utility of intermediate 10 is illustrated by the first synthesis of (-)-gabosine L, as well as the new synthesis of (-)-gabosine A, (-)-gabosine B, (-)-gabosine N and (-)-gabosine O. The chemical structure and the absolute configuration of (-)-gabosine L are confirmed by its total synthesis.

Abstract
(+)-epi-Epoformin (1), is a fungal cyclohexene epoxide isolated together with diplopimarane and sphaeropsidins A and C, a nor-ent-pimarane and two pimaranes, from the culture filtrates of Diplodia quercivora, a fungal pathogen for cork oak in Sardinia, Italy. Compound 1 possesses a plethora of biological activities, including antifungal, zootoxic and phytotoxic activity. The last activity and the peculiar structural feature of 1 suggested to carry out a structure activity relationship study, preparing eight key hemisynthetic derivatives and the phytotoxicity was assayed. The complete spectroscopic characterization and the activity in the etiolated wheat coleoptile bioassay of all the compounds is reported. Most of the compounds inhibited growth and some of them had comparable or higher activity than the natural product and the reference herbicide Logran. As regards the structure-activity relationship, the carbonyl proved to be essential for their activity of 1, as well as the conjugated double bond, while the epoxide could be altered with no significant loss.

Abstract
![]()
The
acyloxyallylation of unprotected aldoses was first demonstrated
more than a decade ago as a potentially elegant two-carbon homologation
of reducing sugars (upon ozonolysis); however, its application in
real case syntheses remained scarce. Following up on such a successful
showcase and to answer several pending questions about this attractive
transformation, we engaged in an in depth methodological reinvestigation.
The epimeric tetroses l-erythrose and d-threose
in unprotected and protected form were successfully applied to the
indium and also zinc-mediated acyloxyallylation, with the latter being
a first for an unprotected sugar. The investigation largely benefited
from the choice of these more exotic starting materials as it allowed
unambiguous identification/quantification of the hexose-products which
are available as authentic reference materials. The observed diastereoselectivities
indicate a strong substrate control (stereochemistry at O2), and the influence of the reagent’s structure on the selectivity
was investigated in great detail. A strong facial diastereodivergence
between related protected and unprotected structures was demonstrated
and an unexpected, pronounced principle difference in performance
between indium and zinc was revealed.

Abstract
The first total synthesis of (+)-gabosine J and that of the epimer at C4 of its enantiomer have been accomplished through an enantioselective approach from a common intermediate 1. These syntheses have allowed us to establish the correct relative configuration of the natural metabolite, which was originally misassigned. This work, together with our former syntheses of other gabosines and related compounds, validates enone 1 as a general synthetic precursor for this kind of carbasugars.
