The biosynthesis of C5-C25 terpenoid compounds.
This review covers recently-published experimental information on the biosynthesis of terpenoids in the range C5-C25. In addition to sections on the mevalonate and mevalonate-independent (deoxyxylulose phosphate) pathways, the review considers in turn hemiterpenoids, polyprenyl diphosphate synthases, monoterpenoids, sesquiterpenoids, diterpenoids, and sesterterpenoids. The literature from Janua...
متن کاملSynthesis of the C9–C25 Subunit of Spirastrellolide B
The synthesis of the C9-C25 subunit of the marine natural product spirastrellolide B is reported. The key synthetic features included the union of the two key fragments 5 and 6 via a Suzuki-Miyaura coupling reaction and a late-stage, one-pot sequential deprotection/cascade Achmatowicz rearrangement-spiroketalization to install the key spirocyclic intermediate present in the C9-C25 fragment of s...
متن کاملDeveloping an Embosi (Bantu C25) Speech Variant Dictionary to Model Vowel Elision and Morpheme Deletion
This paper investigates vowel elision and morpheme deletion in Embosi (Bantu C25), an under-resourced language spoken in the Republic of Congo. We propose that the observed morpheme deletion is morphological, and that vowel elision is phonological. The study focuses on vowel elision that occurs across word boundaries between the contact of long/short vowels (i.e. CV[long] # V[short].CV), and be...
متن کاملAn expedient synthesis of spiroketals: model studies for the calyculin C16–C25 fragment
A new short strategy to prepare the spiroketal fragment of calyculins is presented. A novel Seyferth–Gilbert type homologation of hindered lactols to the corresponding alkynes has been achieved for the first time. The spirocyclization was achieved efficiently via a DIHMA (double intramolecular hetero-Michael addition) process of this hindered ynone. The spirocyclization rate is not dependent on...
متن کاملDraft Genome Sequence of Lactobacillus crispatus C25 Isolated from Chicken Cecum
Lactic acid bacteria are important members of the gut microbiota of humans and animals. Here, we present the genome sequence of Lactobacillus crispatus strain C25, originally isolated from the cecum of 4-week-old chicken fed a standard diet. This isolate represents a potential probiotic strain for poultry.
