Regio-, stereo-, and enantioselective synthesis of cyclobutanols by means of the photoaddition of 1,3-dioxin-4-ones and lipase-catalyzed acetylation

Homochiral cis-2-hydroxymethylcyclobutanols, their all cis 3-methyl, and 4-hydroxymethyl derivatives were synthesized from 1,3-dioxin-4-ones via cyclobutane ring formation by [2+2]photocycloaddition, dioxanone ring cleavage, and reduction, followed by lip

SYNTHESIS OF 1,3-DIOXIN-4-ONES AND THEIR USE IN SYNTHESIS. XI. 2,2-DIMETHYL-1,3-DIOXIN-4-ONE AS A SYNTHETIC EQUIVALENT OF FORMYLKETENE: SYNTHESIS OF HETEROCYCLIC COMPOUNS

Cycloaddition of formylketene generated in situ by thermolysis of 2,2-dimethyl-1,3-dioxin-4-one with N-benzhydrylidenebenzylamine yields 3-benzyl-2,2-diphenyl-1,3-oxazin-4-one.Analogous reactions with a carbodiimide, cyanamide, and keteneacetal afford the corresponding 4 + 2 cycloadducts.Reaction of formylketene with 3-amino-2-butenamides affords 4-hydroxy-2-pyridones having a C-2 unit at the 3-position.Keywords: 1,3-dioxin-4-one;formylketene; cycloaddition;1,3-oxazin-4-one; 4-pyrone; 3-acetyl-4-hydroxy-2-pyridone; thermolysis; uracil derivative.

SYNTHESIS OF 1,3-DIOXIN-4-ONES UNSUBSTITUTED AT THE 5- AND 6-POSITIONS AND THEIR PHOTOADDITION TO ALKENES

A general synthetic method of 5,6-unsubstituted 1,3-dioxin-4-ones and their photoaddition to alkenes are described.The photoadducts thus obtained were found to give, merely by refluxing in water, alkanes having carboxaldehyde and acetic acid appendages at the vicinal position.
