Age-friendly neighbourhood planning and design guidelines: a Singapore case study
No full textAge-Friendly Neighbourhood Planning and Design Guidelines: A Singapore Case Study provides evidence-based research and examples of existing good practices on health-enabling, age-friendly neighbourhood provision. These relate to the planning and design of outdoor spaces and enabling opportunities for active, healthy ageing. Importantly, our research prioritises the need to engage with older people when creating neighbourhood environments that contribute to healthy ageing in place.The book and its supplementary toolkits touches on 3 main stages of age-friendly neighbourhood project — planning (environmental audit), implementation (planning and design guidelines) and evaluation of progress made (post-implementation review). We hope that these materials will contribute to the ongoing discourse of how to (re)envision urban neighbourhoods to enhance health and quality of life as people age. Needless to say, they do not supersede but support existing guidelines or regulations to improve everyday neighbourhood environment for healthy ageing in place.Co-creation with older people is a central tenet of our research on ageing urbanism at the Lee Kuan Yew Centre for Innovative Cities. The Lee Li Ming Programme in Ageing Urbanism conducts applied research on built environment and health of ageing population, arguing for a more integrated environmental, social and spatial approach to identify the connection between the built environment, health and quality of life that can inform the design for age-friendly neighbourhoods and communities
Meaning of age-friendly neighbourhood: an exploratory study with older adults and key informants in Singapore
No full textThis study explores the concept of age-friendly neighbourhood as understood by older adults and key informants (local service providers, professionals and public officials) in Singapore. Data are collected through key informant interviews (n = 15) and focus group discussion (n = 80, age 52–82 years) in three study neighbourhoods in Singapore that have relatively high percentages of older populations. Older people and key informants are asked to describe in their own words what an age-friendly neighbourhood means to them. Qualitative content analyses are performed on the interview and discussion data to arrive at a thematic understanding of age-friendly neighbourhood in Singapore. Inclusiveness, social environment, physical environment, sense of place and safety are five key characteristics that participants have used to describe age-friendly neighbourhood. While there are widely established frameworks on age-friendly cities and communities, the findings highlight that context-specific and experiential understandings of age-friendly neighbourhood initiatives are important

Selective C3-alkenylation of oxindole with aldehydes using heterogeneous CeO2 catalyst
No full textWe report herein that a commercially available CeO2 is an active and reusable catalyst for the C3-selective alkenylation of oxindole with aldehydes under solvent-free conditions. This. catalytic method is generally applicable to different aromatic and aliphatic aldehydes, giving 3-alkyledene-oxindoles in high yields (87%-99%) and high stereoselectivities (79%-93% to E-isomers). This is the first example of the catalytic synthesis of 3-alkenyl-oxindoles from oxindole and various aliphatic aldehydes. The Lewis acid-base interaction between Lewis acid sites on CeO2 and benzaldehyde was studied by in situ IR. The structure-activity relationship study using CeO2 catalysts with different sizes suggests that defect-free CeO2 surface is the active site for this reaction.

Direct Phenolysis Reactions of Unactivated Amides into Phenolic Esters Promoted by a Heterogeneous CeO2 Catalyst
No full textThe direct catalytic esterification of amides that leads to the construction of C-O bonds through the cleavage of amide C-N bonds is a highly attractive strategy in organic synthesis. While aliphatic and aromatic alcohols can be readily used for the alcoholysis of activated and unactivated amides, the introduction of phenols is more challenging due to their lower nucleophilicity in the phenolysis of unactivated amides. Herein, we demonstrate that phenols can be used for the phenolysis of unactivated amides into the corresponding phenolic esters using a simple heterogenous catalytic system based on CeO2 under additive-free reaction conditions. The method tolerates a broad variety of functional groups (>50 examples) in the substrates. Results of kinetic studies afforded mechanistic insights into the principles governing this reaction, suggesting that the cooperative effects of the acid-base functions of catalysts would be of paramount importance for the efficient progression of the C-N bond breaking process, and consequently, CeO2 showed the best catalytic performance among the catalysts explored
