Novel synthesis method of ester free trimethylene carbonate derivatives

Ester free poly(trimethylene carbonate) (PTMC) derivatives show biocompatibility and biodegradability and do not generate any acidic compounds after decomposition. Their syntheses methods are limited however, hampering their material application. Herein, we established a novel synthesis route of ester free trimethylene carbonate (TMC) derivatives. The novel synthesis route was described using six aldehydes and one ketone as starting compounds. The key reaction is the selective deprotection from two protected hydroxyl groups in the cyclic acetal structure by diisobutylaluminium hydride. This novel synthesis route means that it is possible to convert aldehyde group to ether groups in the side chain of TMC. Conventionally, only a substituent derived from a primary alcohol was introduced into the side chain. We therefore succeeded in decreasing the number of reaction steps from five to three, compared with the conventional route. Furthermore, the development of a novel synthesis route enabled the introduction of substituents derived from secondary alcohols, anticipating the creation of further types of ester free TMC derivatives.

DIOXABORINANES AND USES THEREOF

A dioxaborinane compound, or salt thereof, where boron has two oxy substituents, each independently substituted with H, alkyl, alkenyl, aryl, -C(O)R3, -C(O)OR3, -C(O)NHR3, or the two oxy substituents, together with the oxygen atoms to which they are bonded, join to form a 5- or 6-membered ring; and R3 is H, alkyl, alkenyl, or aryl, where the alkyl and alkenyl are optionally interrupted with one or more oxygen or sulfur atoms; and where boron also has the substituent -L-X1-PG1; where L may be absent, or alkylenyl, alkenylenyl, or arylene, where the alkylenyl and alkenylenyl are optionally interrupted with one or more oxygen or sulfur atoms; X1 is absent, or is amino, oxo, thio, or phosphino; and PG1 is a polymerizable group. The dioxaborinane compound can be used as a wood preservative.

The anomalous reactivity of the bis(dibutylstannylene) acetal of pentaerythritol: A case of triple activation

The only dibutyltin derivative of pentaerythritol which is observed by refluxing with dibutyltin oxide in methanol is a bis(dibutylstannylene) acetal. This is converted to the expected dibenzyl ether with benzyl bromide, in the presence of tetraethylammon
