- Botrylactone: New interest in an old molecule - Review of its absolute configuration and related compounds
-
The absolute configuration of botrylactone, a unique compound with an interesting polyketide lactone skeleton with two oxirane bridges previously isolated from Botrytis cinerea and described as a powerful antibiotic, has been reviewed on the basis of sign of the optical rotation, NOE experiments and NMR method. The isolation of 7-deoxybotrylactone and 5-hydroxy-7-(4-hydroxydec-2(3)- enoyl) botrylactone enables us to characterize an intriguing new family of compounds with this interesting polyketide skeleton. A common biosynthetic origin with botcinin derivatives is proposed. Copyright

- Studies on the biosynthesis of secobotryane skeleton
-
The labelling and coupling patterns of secobotrytrienediol, biosynthesised from [1-13C] and [1,2-13C2]-acetate by the fungus Botrytis cinerea, have been used to define the mode of formation and the biogenetic origin of secobotrytrienediol. [10-2H]-Botrydiol was not incorporated into the secobotryane skeleton. In addition, this feeding experiment led to the isolation of three new unlabelled derivatives possessing a secobotryane skeleton, secobotrydiene-3,10,15-triol, secobotrydiene-3,4,10,15-tetraol, and secobotrytriene-10,12,15-triol.
