## Abstract Photochemical reactions of caffeine with several aliphatic aldehydes are performed. In the reactions with ethanal, propanal and butanal stable 8βacylβ8,9βdihydrocaffeines 2 and 3 together with unreduced 8βacylcaffeines 4 and 8β(Ξ±βhydroxyalkyl)caffeines 6 are produced. Under similar cond
Preliminary results of an examination of factors influencing the stoichiometry and regioselectivity of the Paterno-Btlchi reaction between aliphatic aldehydes and nonsymmetrical allenes are divulged. Surprisingly little regioselectivity was seen with 3-methyl-l,2-butadiene (6); however, l-ethoxy-l,2
