Abstract
The precise synthesis of chiral polymers remains a significant challenge in polymer chemistry, particularly for applications in advanced biomedical and electronic materials. The development of degradable polymers is important for eco-friendly and advanced materials. Here, we introduce a stereo-controlled degradable polymer via cascade enyne metathesis polymerization and enantioselective acetal synthesis through Pd-catalyzed asymmetric hydroamination. This approach allows for the creation of chiral acetal-based polymers with controlled stereochemistry and degradability, highlighting their potential for use in drug delivery and electronic applications. This concept article reviews the background, development, and potential applications of these stereo-controlled degradable polymers.

Abstract
In the presence of an arylboronic acid catalyst, azole-type heterocycles, including purines, tetrazoles, triazoles, indazoles, and benzo-fused congeners, undergo regio- and stereoselective N-glycosylations with furanosyl and pyranosyl trichloroacetimidate donors. The protocol, which does not require stoichiometric activators, specialized leaving groups, or drying agents, provides access to nucleoside analogues and enables late-stage N-glycosylation of azole-containing pharmaceutical agents. A mechanism involving simultaneous activation of the glycosyl donor and acceptor by the organoboron catalyst has been proposed, supported by kinetic analysis and computational modeling.

Abstract
A stereocontrolled degradable polymer was synthesized via living cascade enyne metathesis polymerization. Highly stereodefined N,O-acetal-containing enyne monomers were prepared using the Pd-catalyzed hydroamination of alkoxyallenes and ring-closing metathesis. The resulting chiral polymer exhibited a narrow dispersity window. Block copolymers were prepared not only by sequentially adding nondegradable and degradable monomers but also by using enantiomerically different monomers to produce stereocontrolled blocks. Owing to the hydrolyzable N,O-acetal moiety in the backbone structure, the resulting polymer could degrade under acidic conditions generated using various acid concentrations to control the degradation. Additionally, the aza-Diels-Alder reaction modified the polymer without losing the stereochemistry.

Abstract
We report sequential metal catalysis towards indolocarbazole glycosides. The signature event is highlighted by i) Pd0 -catalyzed addition of indolocarbazole to alkoxyallene combined with ring-closing-metathesis; ii) Ru-catalyzed chemoselective olefin migration; iii) PdII -catalyzed oxidative cyclization to build the bicyclic core structure of the target compounds. This approach gave access to both natural pyranose- and non-natural septanose glycosides. A short formal synthesis of 7-oxostaurosporine was achieved via this strategy.

Abstract
The catalytic asymmetric synthesis of hexahydro-furofuran-3-ol, a key fragment of HIV protease inhibitors, is reported. A signature event is represented by the sequential metal catalysis that combines the Pd-catalyzed asymmetric hydroalkoxylation of ene-alkoxyallene and ring-closing metathesis (RCM). Notably, this unprecedented and highly chemoselective approach allows for a unified access to pyranofuranol and furopyranol derivatives.

Abstract
Alkoxyallenes are easily available and versatile building blocks for the preparation
of a variety of natural products (terpenes, polyketides, alkaloids, amino acids, carbohydrates
etc.) originating from different classes. The synthetic use of the three allene carbon
atoms frequently follows the “normal” reactivity pattern showing that alkoxyallenes
can be regarded as special enol ethers. Additions of alcohols or amines to alkoxyallenes
form vinyl-substituted O,O- or N,O-acetals that are frequently used in ring-closing
metathesis reactions. This methodology delivers crucial heterocyclic units of the target
compounds. Enantioselective additions provide products with high enantiopurity.
Alternatively, an “Umpolung” of reactivity of alkoxyallenes is achieved by lithiation at
C-1 and subsequent reaction with electrophiles, such as alkyl halides, carbonyl
compounds, imines or nitrones. High stereoselectivity of the addition step can be achieved by substrate control
or auxiliary control. The high diastereo- or enantioselectivity is transferred to the subsequent acyclic or cyclic
products. The cyclization of primary addition products occurs efficiently under mild conditions and provides
functionalized dihydrofuran, dihydropyrrole or 1,2-oxazine derivatives. These are valuable intermediates for
the synthesis of a variety of heterocyclic natural products. Nazarov cyclizations or gold catalyzed rearrangements
allow the synthesis of five- and six-membered carbocyclic compounds that are also used for natural
product synthesis.
Dedicated to Dr. Reinhold Zimmer, a pioneer of alkoxyallene chemistry, on the occasion of his 60th
birthday.

Abstract
An efficient route to construct chiral acyclic purine nucleoside analogues via dynamic kinetic resolution of α-purine substituted alkanoic acids is reported. Using ( S)-BTM as the catalyst, diverse chiral acyclic purine nucleoside analogues were obtained in moderate to good yields (up to 93%) and high enantioselectivities (up to 98% ee). Chiral acyclic purine nucleosides could be obtained from the esterified products via reduction reaction, which could then be transferred into Tenofovir analogues.
