Abstract
Herein, we report a highly modular strategy to access spirocyclic scaffolds from abundant starting materials, i.e., cyclic ketones and α-amino or oxamic acids. The sequence proceeds through a straightforward Knoevenagel condensation, followed by a domino Giese-type reaction/base-mediated cyclization process, to deliver a broad scope of polar spirocyclic scaffolds in good to excellent yields. The products can be readily diversified, thus increasing the versatility of our method to gain rapid access to libraries of potential druglike molecules.

Abstract
The first (3 + 2)/(3 + 2) sequential annulation of γ-vinyl allenoates with alkylidenemalononitriles enabled by phosphine catalysis has been reported. A broad range of structurally dense tetra- and penta-substituted bicyclic[3,3,0]octene derivatives, containing a quaternary center and three sequential stereogenic center, were synthesized in good to excellent yields. In this approach, three new C-C bonds are formed in one pot, and εC and αC of γ-vinyl allenoate are two electrophilic centers, whereas its γC exhibits nucleophilic reactivity.

Abstract
![]()
A stereoselective
intramolecular Tsuji–Trost cascade cyclization
of (homo)allylic vicinal diacetates with a pendant β-ketoamide
or related carbon nucleophile to give γ-lactam-fused vinylcyclopropanes
is reported. In addition to two new rings, the products contain three
new C–C stereocenters (two of which are quaternary) with a
9:1 dr. Moreover, the reaction proceeds in >94% enantiospecificity
with optically enriched starting materials, using an inexpensive carbohydrate
as the source of chirality.
