Abstract
Griseoviridin is a group A streptogramin natural product from Streptomyces with broad-spectrum antibacterial activity. A hybrid polyketide-nonribosomal peptide, it comprises a 23-membered macrocycle, an embedded oxazole motif, and a macrolactone with a unique ene-thiol linkage. Recent analysis of the griseoviridin biosynthetic gene cluster implicated SgvP, a cytochrome P450 monooxygenase, in late-stage installation of the critical C-S bond. While genetic and crystallographic experiments provided indirect evidence to support this hypothesis, the exact function of SgvP has never been confirmed biochemically. Herein, we report a convergent total synthesis of pre-griseoviridin, the putative substrate of P450 SgvP and precursor to griseoviridin. Our strategy features concise and rapid assembly of two fragments joined via sequential peptide coupling and Stille macrocyclization. Access to pre-griseoviridin then enabled in vitro validation of SgvP as the C-S bond-forming P450 during griseoviridin biosynthesis, culminating in a nine-step chemoenzymatic synthesis of griseoviridin.

Abstract
Covalent Organic Frameworks (COFs) have recently emerged as light-harvesting devices, as well as elegant heterogeneous catalysts. The combination of these two properties into a dual catalyst has not yet been explored. We report a new photosensitive triazine-based COF, decorated with single Ni sites to form a dual catalyst. This crystalline and highly porous catalyst shows excellent catalytic performance in the visible-light-driven catalytic sulfur-carbon cross-coupling reaction. Incorporation of single transition metal sites in a photosensitive COF scaffold with two-component synergistic catalyst in organic transformation is demonstrated for the first time.

Abstract
The palladium-catalyzed intramolecular dearomative Heck reaction of 2,3-disubstituted indoles serves as an access to spiro-indoline products. Herein, we report an efficient construction of indoline/indolenine core stuctures via a dearomative Heck reaction of simple 2,3-disubstituted indoles with all-carbon tethers and the subsequent aza-semipinacol rearrangement. The Heck reaction features a high C2-selectivity, and the stereospecific aryl/alkyl migration selectivity has been investigated by DFT calculations. Using this method, we accomplished the formal total synthesis of akuammiline alkaloids vincorine.

Abstract
Griseoviridin (GV) is a broad-spectrum antibiotic with antibacterial and antifungal activity. In the GV biosynthetic pathway, SgvP catalyzes formation of the carbon-sulfur bond in GV. Herein, we report the recombinant expression and characterization of SgvP from Streptomyces griseoviridis NRRL2427. We also present the 2.6 Å crystal structure of SgvP, which is the first structure of a cytochrome P450 involved in carbon-sulfur bond formation in GV. Structural analysis indicates that Pro237 in the I-helix of SgvP may play a critical role in dioxygen binding and proton transfer during the catalytic cycle. Of the three channels we observed in SgvP, channel 3 may be essential for substrate ingress and egress from the active site, while channels 1 and 2 may be the solvent and water pathway, respectively. DATABASE Coordinate and structure factor were deposited in the Protein Data Bank database under the accession number 4MM0.

Abstract
A short and efficient synthesis of model spiroiminals that have the same stereochemistry as marineosins A and B, but different conformations, was carried out in six or seven steps from 6-methyltetrahydropyran-2-one. These spiroiminals were also prepared biomimetically by reduction of an enol ether. A more highly substituted spiroiminal with the same stereochemistry and conformation as marineosin A was prepared in 11 steps from parasorbic acid. A macrocyclic pyrrole lactone was prepared stereospecifically in 10 steps. A five-step sequence converted the lactone to a late hemi-iminal intermediate that has resisted the methylation and spiroiminal formation that would lead to marineosin A.

Abstract
Chiral surfaces attract increasing interest due to their vital role in a variety of scientific fields, such as chiral separation and heterogeneous enantioselective catalysis. The most urgent issue in research on such two-dimensional chirality is a lack of methodologies that recognize molecular chirality on a surface. Here we show that the chiral molecular tips enable for the first time discrimination of enantiomers on a single-molecule basis. The chiral selectivity is attributed to favorable chemical interactions that the molecular tips form with only one of two enantiomers. The stereoselective observation reveals spatial distribution of the enantiomers on a surface at the molecular level. The chiral molecular tips open a way for control of organization of enantiomers toward the advanced functionality of these chiral surfaces through knowledge on pivotal roles of chirality on molecular assemblies as shown here.

Abstract
[reaction: see text] Lantibiotics are a class of lanthionine (and/or beta-methyllanthionine)-containing peptides with antibioitic activity against Gram-positive bacteria. As part of our research effort directed toward the synthesis and mechanistic study of the lantibiotic peptide mersacidin (1), we report stereoselective syntheses of orthogonally protected beta-methylcysteine (beta-MeCys) and beta-methyllanthionine (beta-MeLan), two key nonnatural amino acid components of the mersacidin architecture.
